.SH NAME
pam_getenv \- returns the value for a PAM environment name
.SH SYNOPSIS

\fBcc\fR [ \fIflag\fR ... ] \fIfile\fR ... \fB-lpam\fR [ \fIlibrary\fR ... ]

.SH DESCRIPTION
.sp
.LP
The \fBpam_getenv()\fR function searches the \fBPAM\fR handle \fIpamh\fR for a
value associated with \fIname\fR. If a value is present, \fBpam_getenv()\fR
makes a copy of the value and returns a pointer to the copy back to the calling
application. If no such entry exists, \fBpam_getenv()\fR returns  \fINULL\fR.
It is the responsibility of the calling application to free the memory returned
by \fBpam_getenv()\fR.
.SH RETURN VALUES
.sp
.LP
If successful, \fBpam_getenv()\fR returns a copy of the \fIvalue\fR associated
with \fIname\fR in the \fBPAM\fR handle; otherwise, it returns a  \fINULL\fR
pointer.

The interfaces in  \fBlibpam\fR are MT-Safe only if each thread within the
multithreaded application uses its own \fBPAM\fR handle.
