PAM_GETENV(3)            BSD Library Functions Manual            PAM_GETENV(3)

NAME
     pam_getenv -- retrieve the value of a PAM environment variable

LIBRARY
     Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS
     #include <sys/types.h>
     #include <security/pam_appl.h>

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

DESCRIPTION
     The pam_getenv function returns the value of an environment variable.  Its semantics are similar to
     those of getenv(3), but it accesses the PAM context's environment list instead of the application's.

RETURN VALUES
     The pam_getenv function returns NULL on failure.
