Log message infrastructure.
| #define EXIF_LOG_NO_MEMORY | ( | l, | |
| d, | |||
| s ) |
| const char * exif_log_code_get_message | ( | ExifLogCode | code | ) |
Return a verbose description of the given class of error log.
| [in] | code | logging message class |
| const char * exif_log_code_get_title | ( | ExifLogCode | code | ) |
Return a textual description of the given class of error log.
| [in] | code | logging message class |
| void exif_log_free | ( | ExifLog * | log | ) |
Delete instance of ExifLog.
| [in] | log | ExifLog |
| ExifLog * exif_log_new | ( | void | ) |
| void exif_log_set_func | ( | ExifLog * | log, |
| ExifLogFunc | func, | ||
| void * | data ) |
