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.
