PAM_GETENVLIST
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.
