PAM_GETENV(3PAM) PAM Library Functions PAM_GETENV(3PAM)

pam_getenv - returns the value for a PAM environment name

cc [ flag ... ] file ... -lpam [ library ... ]
#include <security/pam_appl.h>
char *pam_getenv(pam_handle_t *pamh, const char *name);

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().

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