| char * | xi_str_dup (const char *s) |
| int | xi_str_copy_untiln (char *dst, size_t dst_size, const char *src, char delim) |
| Copies `src` string into `dst`, but stops whenever `delim` is reached or the `dst_size` is exceeded. | |
| time_t | xi_mktime (struct tm *t) |
| Converts from `tm` to `time_t`. | |
| struct tm * | xi_gmtime (time_t *t) |
| This just wraps system's `gmtime()`, it a facade for future use. | |
| char * | xi_replace_with (char p, char r, char *buffer, size_t max_chars) |
| Replaces `p` with `r` for every `p` in `buffer`. | |

Function Documentation
| struct tm* xi_gmtime | ( | time_t * | t ) | [read] |
This just wraps system's `gmtime()`, it a facade for future use.
Definition at line 165 of file xi_helpers.c.
| time_t xi_mktime | ( | struct tm * | t ) |
Converts from `tm` to `time_t`.
- Note:
- This code assumes that unsigned long can be converted to `time_t`. A `time_t` should not be wider than `unsigned long`, since this would mean that the check for overflow at the end could fail.
- This implementation had been copied from MINIX C library. Which is 100% compatible with our license.
- This function does not take into account the timezone or the `dst`, it just converts `tm` structure using date and time fields (i.e. UTC).
| char* xi_replace_with | ( | char | p, |
| char | r, | ||
| char * | buffer, | ||
| size_t | max_chars | ||
| ) |
Replaces `p` with `r` for every `p` in `buffer`.
- Returns:
- Pointer to converted buffer.
- Note:
- This function assumes that the buffer is terminated with `\0`.
Definition at line 170 of file xi_helpers.c.
| int xi_str_copy_untiln | ( | char * | dst, |
| size_t | dst_size, | ||
| const char * | src, | ||
| char | delim | ||
| ) |
Copies `src` string into `dst`, but stops whenever `delim` is reached or the `dst_size` is exceeded.
- Returns:
- Number of copied characters or -1 if an error occurred.
Definition at line 31 of file xi_helpers.c.
| char* xi_str_dup | ( | const char * | s ) |
- Note:
- Needed to avoid using `strdup()` which can cause some problems with `free()`, because of buggy `realloc()` implementations.
- Returns:
- Duplicated string or null in case of memory allocation problem.
Definition at line 19 of file xi_helpers.c.
