PAM_STRERROR(3PAM) PAM Library Functions PAM_STRERROR(3PAM)

NAME

pam_strerror - get PAM error message string

SYNOPSIS

cc [ flag... ] file... -lpam [ library... ]
#include <security/pam_appl.h>


const char *pam_strerror(pam_handle_t*pamh, int errnum);

DESCRIPTION

The pam_strerror() function maps the PAM error number in errnum to a
PAM error message string, and returns a pointer to that string. The
application should not free or modify the string returned.


The pamh argument is the PAM handle obtained by a prior call to
pam_start(). If pam_start() returns an error, a null PAM handle
should be passed.

ERRORS

The pam_strerror() function returns the string "Unknown error" if
errnum is out-of-range.
