GENDERS_ERRNUM(3) LIBGENDERS GENDERS_ERRNUM(3)NAME
genders_errnum, genders_strerror, genders_errormsg, genders_perror - genders error routines
SYNOPSIS
#include <genders.h>
int genders_errnum(genders_t handle);
char *genders_strerror(int errnum);
char *genders_errormsg(genders_t handle);
void genders_perror(genders_t handle, const char *msg);
DESCRIPTION
genders_errnum() returns the error code stored in handle.
genders_strerror() returns a pointer to a string describing the error code errnum.
Generally, an error code is retrieved by genders_errnum() and then passed to genders_strerror().
genders_errormsg() returns a pointer to a string describing the error stored in handle. It is logically equivalent to:
char *genders_strerror(genders_errnum(genders_t handle));
genders_perror() is similar to perror(3). It produces a message on standard error output, describing the error stored in handle. If msg
is not NULL, the string pointed to by msg, a colon, and a blank are printed before the error message.

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

handle has an incorrect magic number. handle does not point to a genders handle or handle has already been destroyed.
