man genders_errors (Fonctions bibliothèques) - genders_errnum, genders_strerror, genders_errormsg, genders_perror - get information about recent genders errors
NAME
genders_errnum, genders_strerror, genders_errormsg, genders_perror - get information about recent genders errors
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 string describing the error code errnum.
genders_errormsg() returns a string describing the error code stored in handle. It 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.
In general, genders_errnum(), genders_strerror(),
genders_errormsg(), and genders_perror() should be used
immediately after a genders C API function returns an error. Thus,
these functions can return information about the most recent error
that has occurred.
RETURN VALUES
genders_errnum() returns the error code stored in handle.
genders_strerror() and genders_errormsg(), return a
pointer to a string describing the error code stored in handle.
