const char *pam_strerror(pam_handle_t *pamh,
int errnum);
DESCRIPTION
pam_strerror()
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.
APPLICATION USAGE
Refer to
pam(3)
for information on thread-safety of PAM interfaces.
ERRORS
pam_strerror()
returns
NULL
if
errnum
is out-of-range.
