.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lpam\fR [ \fIlibrary\fR... ]
#include <security/pam_appl.h>

\fBconst char *\fR\fBpam_strerror\fR(\fBpam_handle_t*\fR\fIpamh\fR, \fBint\fR \fIerrnum\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBpam_strerror()\fR function maps the \fBPAM\fR error number in \fIerrnum\fR to a \fBPAM\fR error message string, and returns a pointer to that string. The application should not free or modify the string returned.
.sp
.LP
The \fIpamh\fR argument is the  \fBPAM\fR handle obtained by a prior call to \fBpam_start()\fR. If \fBpam_start()\fR returns an error, a null \fBPAM\fR handle should be passed.
.SH ERRORS
.sp
.LP
The \fBpam_strerror()\fR function returns the string "Unknown error" if \fIerrnum\fR is out-of-range.
