Function Documentation
void iniparser_dump | ( | dictionary * | d, |
FILE * | f | ||
) |
Dump a dictionary to an opened file pointer.
- Parameters:
-
d Dictionary to dump. f Opened file pointer to dump to.
- Returns:
- void
This function prints out the contents of a dictionary, one element by line, onto the provided file pointer. It is OK to specify stderr
or stdout
as output files. This function is meant for debugging purposes mostly.
Definition at line 178 of file iniparser.c.
void iniparser_dump_ini | ( | dictionary * | d, |
FILE * | f | ||
) |
Save a dictionary to a loadable ini file.
- Parameters:
-
d Dictionary to dump f Opened file pointer to dump to
- Returns:
- void
This function dumps a given dictionary into a loadable ini file. It is Ok to specify stderr
or stdout
as output files.
Definition at line 206 of file iniparser.c.
void iniparser_dumpsection_ini | ( | dictionary * | d, |
char * | s, | ||
FILE * | f | ||
) |
Save a dictionary section to a loadable ini file.
- Parameters:
-
d Dictionary to dump s Section name of dictionary to dump f Opened file pointer to dump to
- Returns:
- void
This function dumps a given section of a given dictionary into a loadable ini file. It is Ok to specify stderr
or stdout
as output files.
Definition at line 244 of file iniparser.c.
int iniparser_find_entry | ( | dictionary * | ini, |
const char * | entry | ||
) |
Finds out if a given entry exists in a dictionary.
- Parameters:
-
ini Dictionary to search entry Name of the entry to look for
- Returns:
- integer 1 if entry exists, 0 otherwise
Finds out if a given entry exists in the dictionary. Since sections are stored as keys with NULL associated values, this is the only way of querying for the presence of sections in a dictionary.
Definition at line 500 of file iniparser.c.
void iniparser_freedict | ( | dictionary * | d ) |
Free all memory associated to an ini dictionary.
- Parameters:
-
d Dictionary to free
- Returns:
- void
Free all memory associated to an ini dictionary. It is mandatory to call this function before the dictionary object gets out of the current context.
Definition at line 743 of file iniparser.c.
int iniparser_getboolean | ( | dictionary * | d, |
const char * | key, | ||
int | notfound | ||
) |
Get the string associated to a key, convert to a boolean.
- Parameters:
-
d Dictionary to search key Key string to look for notfound Value to return in case of error
- Returns:
- integer
This function queries a dictionary for a key. A key as read from an ini file is given as "section:key". If the key cannot be found, the notfound value is returned.
A true boolean is found if one of the following is matched:
- A string starting with 'y'
- A string starting with 'Y'
- A string starting with 't'
- A string starting with 'T'
- A string starting with '1'
A false boolean is found if one of the following is matched:
- A string starting with 'n'
- A string starting with 'N'
- A string starting with 'f'
- A string starting with 'F'
- A string starting with '0'
The notfound value returned if no boolean is identified, does not necessarily have to be 0 or 1.
Definition at line 471 of file iniparser.c.
double iniparser_getdouble | ( | dictionary * | d, |
const char * | key, | ||
double | notfound | ||
) |
Get the string associated to a key, convert to a double.
- Parameters:
-
d Dictionary to search key Key string to look for notfound Value to return in case of error
- Returns:
- double
This function queries a dictionary for a key. A key as read from an ini file is given as "section:key". If the key cannot be found, the notfound value is returned.
Definition at line 430 of file iniparser.c.
int iniparser_getint | ( | dictionary * | d, |
const char * | key, | ||
int | notfound | ||
) |
Get the string associated to a key, convert to an int.
- Parameters:
-
d Dictionary to search key Key string to look for notfound Value to return in case of error
- Returns:
- integer
This function queries a dictionary for a key. A key as read from an ini file is given as "section:key". If the key cannot be found, the notfound value is returned.
Supported values for integers include the usual C notation so decimal, octal (starting with 0) and hexadecimal (starting with 0x) are supported. Examples:
"42" -> 42 "042" -> 34 (octal -> decimal) "0x42" -> 66 (hexa -> decimal)
Warning: the conversion may overflow in various ways. Conversion is totally outsourced to strtol(), see the associated man page for overflow handling.
Credits: Thanks to A. Becker for suggesting strtol()

int iniparser_getnsec | ( | dictionary * | d ) |
Get number of sections in a dictionary.
- Parameters:
-
d Dictionary to examine
- Returns:
- int Number of sections found in dictionary
This function returns the number of sections found in a dictionary. The test to recognize sections is done on the string stored in the dictionary: a section name is given as "section" whereas a key is stored as "section:key", thus the test looks for entries that do not contain a colon.
This clearly fails in the case a section name contains a colon, but this should simply be avoided.
This function returns -1 in case of error.
Definition at line 112 of file iniparser.c.
char** iniparser_getseckeys | ( | dictionary * | d, |
char * | s | ||
) |
Get the number of keys in a section of a dictionary.
- Parameters:
-
d Dictionary to examine s Section name of dictionary to examine
- Returns:
- pointer to statically allocated character strings
This function queries a dictionary and finds all keys in a given section. Each pointer in the returned char pointer-to-pointer is pointing to a string allocated in the dictionary; do not free or modify them.
This function returns NULL in case of error.
Definition at line 317 of file iniparser.c.
char* iniparser_getsecname | ( | dictionary * | d, |
int | n | ||
) |
Get name for section n in a dictionary.
- Parameters:
-
d Dictionary to examine n Section number (from 0 to nsec-1).
- Returns:
- Pointer to char string
This function locates the n-th section in a dictionary and returns its name as a pointer to a string statically allocated inside the dictionary. Do not free or modify the returned string!
This function returns NULL in case of error.
Definition at line 143 of file iniparser.c.
int iniparser_getsecnkeys | ( | dictionary * | d, |
char * | s | ||
) |

) |
Get the string associated to a key.
- Parameters:
-
d Dictionary to search key Key string to look for def Default value to return if key not found.
- Returns:
- pointer to statically allocated character string
This function queries a dictionary for a key. A key as read from an ini file is given as "section:key". If the key cannot be found, the pointer passed as 'def' is returned. The returned char pointer is pointing to a string allocated in the dictionary, do not free or modify it.
Definition at line 368 of file iniparser.c.
static line_status iniparser_line | ( | const char * | input_line, |
char * | section, | ||

- Parameters:
-
ininame Name of the ini file to read.
- Returns:
- Pointer to newly allocated dictionary
This is the parser for ini files. This function is called, providing the name of the file to be read. It returns a dictionary object that should not be accessed directly, but through accessor functions instead.
The returned dictionary must be freed using iniparser_freedict().

- Parameters:
-
s String to convert.
- Returns:
- ptr to statically allocated string.
This function returns a pointer to a statically allocated string containing a lowercased version of the input string. Do not free or modify the returned string! Since the returned string is statically allocated, it will be modified at each function call (not re-entrant).
Definition at line 44 of file iniparser.c.
static char* strstrip | ( | const char * | s ) | [static] |
Remove blanks at the beginning and the end of a string.
- Parameters:
-
s String to parse.
- Returns:
- ptr to statically allocated string.
This function returns a pointer to a statically allocated string, which is identical to the input string, except that all blank characters at the end and the beg. of the string have been removed. Do not free or modify the returned string! Since the returned string is statically allocated, it will be modified at each function call (not re-entrant).
