#define econf_setValue | ( | kf, | |
group, | |||
key, | |||
value | |||
) |
Generic macro calls setter function depending on value type.
Use: econf_setValue(econf_file *key_file, char *group, char *key, generic value);
Replace generic with one of the supported value types. Supported Types: int, long, unsigned int, unsigned long, float, double, string (as *char). Note: Does not detect "yes", "no", 1 and 0 as boolean type. If you want to set a bool value use "true" or "false" or use setBoolValue() directly.
Definition at line 106 of file libeconf.h.
#define econf_free | ( | value | ) |
Generic macro to free memory allocated by econf_ functions.
Use: econf_free(generic value);
Replace generic with one of the supported value types. Supported Types: char** and econf_file*.

econf_err econf_readFile | ( | econf_file ** | result, |
const char * | file_name, | ||
const char * | delim, | ||
const char * | comment | ||
) |
Process the file of the given file_name and save its contents into key_file object.
result | content of parsed file. |
file_name | absolute path of parsed file |
delim | delimiters of key/value e.g. "\t =". If delim contains space characters AND none space characters, multiline values are not parseable. |
comment | array of characters which define the start of a comment |
Usage:
econf_err econf_readFileWithCallback | ( | econf_file ** | result, |
const char * | file_name, | ||
const char * | delim, | ||
const char * | comment, | ||
bool(*)(const char *filename, const void *data) | callback, | ||
const void * | callback_data | ||
) |
Process the file of the given file_name and save its contents into key_file object.
The user defined function will be called in order e.g. to check the correct file permissions.
result | content of parsed file. |
file_name | absolute path of parsed file |
delim | delimiters of key/value e.g. "\t =". If delim contains space characters AND none space characters, multiline values are not parseable. |
comment | array of characters which define the start of a comment |
callback | function which will be called for the given filename. This user defined function has the pathname as parameter and returns true if this file can be parsed. If not, the parsing will be aborted and ECONF_PARSING_CALLBACK_FAILED will be returned. |
callback_data | pointer which will be given to the callback function. |
Usage:
Default behaviour if entries have the same name in one file: The first hit will be returned. Further entries will be ignored. This can be changed by setting the option JOIN_SAME_ENTRIES (see econf_newKeyFile_with_options). In that case entries with the same name will be joined to one single entry.
econf_err econf_mergeFiles | ( | econf_file ** | merged_file, |
econf_file * | usr_file, | ||
econf_file * | etc_file | ||
) |
Merge the contents of two key_files objects.
Entries in etc_file will be preferred. Comment and delimiter tag will be taken from usr_file. This can be changed by calling the functions econf_set_comment_tag and econf_set_delimiter_tag.
merged_file | merged data |
usr_file | First data block which has to be merged. |
etc_file | Second data block which has to be merged. |
Usage:
