| PAM Library Functions | pam_getenv(3PAM) |
| | 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); |
| |
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.
