man genders_load_data (Fonctions bibliothèques) - read and parse a genders file
NAME
genders_load_data - read and parse a genders file
SYNOPSIS
#include <genders.h>
int genders_load_data(genders_t handle, const char *filename);
DESCRIPTION
genders_load_data() read and parses the genders file indicated by filename. If filename is NULL, genders_load_data() will attempt to read and parse the default genders file defined by DEFAULT_GENDERS_FILE. handle is a genders handle created by genders_handle_create(3).
After genders_load_data() is called, information about the
genders file is stored in the genders handle passed in. This
information is used by other genders C API functions. All future use
of handle with other genders C API functions will be directly
associated with the genders file indicated by filename (or the
default genders file if filename is NULL).
RETURN VALUES
On success, 0 is returned. On error, -1 is returned, and an error
code is returned in handle. The error code can be retrieved via
genders_errnum(3)
, and a description of the error code can be retrieved via
genders_strerror(3).
Error codes are defined in genders.h.
