pam_strerror - get PAM error message string


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

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


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.


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