pam_getenv(3PAM)					       PAM Library Functions						  pam_getenv(3PAM)

NAME
       pam_getenv - returns the value for a PAM environment name

SYNOPSIS
       cc [ flag ... ] file ... -lpam [ library ... ]
       #include <security/pam_appl.h>

       char *pam_getenv(pam_handle_t *pamh, const char *name);

DESCRIPTION
       The  pam_getenv()  function searches the PAM handle pamh for a value associated with name. If a value is present, pam_getenv() makes a copy
       of the value and returns a pointer to the copy back to the calling application. If no such entry exists, pam_getenv() returns  NULL. It	is
       the responsibility of the calling application to free the memory returned by pam_getenv().

RETURN VALUES
       If successful, pam_getenv() returns a copy of the value associated with name in the PAM handle;
	otherwise, it returns a  NULL pointer.
