GENDERS_LOAD_DATA(3)						    LIBGENDERS						      GENDERS_LOAD_DATA(3)

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  gen-
       ders_errnum(3) , and a description of the error code can be retrieved via genders_strerror(3).  Error codes are defined in genders.h.

ERRORS

       GENDERS_ERR_NULLHANDLE
	      The handle parameter is NULL.  The genders handle must be created with genders_handle_create(3).

       GENDERS_ERR_OPEN
	      The genders file indicated by filename cannot be opened for reading.

       GENDERS_ERR_READ
	      Error reading the genders file indicated by filename.

       GENDERS_ERR_PARSE
	      The genders file indicated by filename is incorrectly formatted.

       GENDERS_ERR_ISLOADED
	      genders_load_data(3) has already been called with handle.

       GENDERS_ERR_OVERFLOW
	      A line in the genders database exceeds the maximum allowed length.

       GENDERS_ERR_OUTMEM
	      malloc(3) has failed internally, system is out of memory.

       GENDERS_ERR_MAGIC
	      handle  has  an  incorrect  magic  number.   handle  does not point to a genders handle or handle has been destroyed by genders_han-
	      dle_destroy(3).

       GENDERS_ERR_INTERNAL
	      An internal system error has occurred.
