+.SH "NAME"
+pam_getenvlist \- getting the PAM environment
+.SH "SYNOPSIS"
+.PP
+\fB#include <security/pam_appl.h>\fR
+.HP 22
+\fBchar\ **\fBpam_getenvlist\fR\fR\fB(\fR\fBpam_handle_t\ *\fR\fB\fIpamh\fR\fR\fB);\fR
+.SH "DESCRIPTION"
+.PP
+The
+\fBpam_getenvlist\fR
+function returns a complete copy of the PAM environment as associated with the handle
+\fIpamh\fR. The PAM environment variables represent the contents of the regular environment variables of the authenticated user when service is granted.
+.PP
+The format of the memory is a malloc()'d array of char pointers, the last element of which is set to NULL. Each of the non\-NULL entries in this array point to a NUL terminated and malloc()'d char string of the form: "\fIname=value\fR".
+.PP
+It should be noted that this memory will never be free()'d by libpam. Once obtained by a call to
+\fBpam_getenvlist\fR, it is the responsibility of the calling application to free() this memory.
+.PP
+It is by design, and not a coincidence, that the format and contents of the returned array matches that required for the third argument of the
+\fBexecle\fR(3)
+function call.
+.SH "RETURN VALUES"
+.PP
+The
+\fBpam_getenvlist\fR
+function returns NULL on failure.
