Read and parse a genders file
#include <genders.h>
int genders_load_data(genders_t handle, const char *filename);
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 GENDERS_DEFAULT_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).
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.
