PAM_GETENVLIST(3)
NAME
pam_getenvlist - getting the PAM environment
SYNOPSIS
#include <security/pam_appl.h> char **pam_getenvlist(pam_handle_t *pamh);
DESCRIPTION
The pam_getenvlist function returns a complete copy of the PAM
environment as associated with the handle pamh. The PAM environment
variables represent the contents of the regular environment variables
of the authenticated user when service is granted.
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: "name=value".
It should be noted that this memory will never be free()'d by libpam.
Once obtained by a call to pam_getenvlist, it is the responsibility of
the calling application to free() this memory.
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
execle(3) function call.
RETURN VALUES
The pam_getenvlist function returns NULL on failure.
