Function Documentation

void iniparser_dump ( dictionary d,
FILE *  f 
)

Dump a dictionary to an opened file pointer.

Parameters:
dDictionary to dump.
fOpened 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 185 of file iniparser.c.

void iniparser_dump_ini ( dictionary d,
FILE *  f 
)

Save a dictionary to a loadable ini file.

Parameters:
dDictionary to dump
fOpened 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 213 of file iniparser.c.

int iniparser_find_entry ( dictionary ini,
char *  entry 
)

Finds out if a given entry exists in a dictionary.

Parameters:
iniDictionary to search
entryName 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 400 of file iniparser.c.

void iniparser_freedict ( dictionary d )

Free all memory associated to an ini dictionary.

Parameters:
dDictionary 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 641 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:
dDictionary to search
keyKey string to look for
notfoundValue 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 371 of file iniparser.c.

double iniparser_getdouble ( dictionary d,
char *  key,
double  notfound 
)

Get the string associated to a key, convert to a double.

Parameters:
dDictionary to search
keyKey string to look for
notfoundValue 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 330 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:
dDictionary to search
keyKey string to look for
notfoundValue 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()

Parameters:
dDictionary to search
keyKey string to look for
notfoundValue to return in case of error
Returns:
integer

int iniparser_getnsec ( dictionary d )

Get number of sections in a dictionary.

Parameters:
dDictionary 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 119 of file iniparser.c.

char* iniparser_getsecname ( dictionary d,
int  n 
)

Get name for section n in a dictionary.

Parameters:
dDictionary to examine
nSection 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 150 of file iniparser.c.

char* iniparser_getstring ( dictionary d,
const char *  key,
char *  def 
)

Get the string associated to a key.

Parameters:
dDictionary to search
keyKey string to look for
defDefault 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 268 of file iniparser.c.

dictionary* iniparser_load ( const char *  ininame )

Parse an ini file and return an allocated dictionary object.

Parameters:
ininameName 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().

Definition at line 529 of file iniparser.c.

int iniparser_setstring ( dictionary ini,
char *  entry,
char *  val 
)

Set an entry in a dictionary.

Parameters:
iniDictionary to modify.
entryEntry to modify (entry name)
valNew value to associate to the entry.
Returns:
int 0 if Ok, -1 otherwise.

If the given entry can be found in the dictionary, it is modified to contain the provided value. If it cannot be found, -1 is returned. It is Ok to set val to NULL.

void iniparser_unset ( dictionary ini,
char *  entry 
)

Delete an entry in a dictionary.

Parameters:
iniDictionary to modify
entryEntry to delete (entry name)
Returns:
void

If the given entry can be found, it is deleted from the dictionary.
