DESCRIPTION

     similar to those of putenv(3), but it modifies the PAM context's environ-
     ment list instead of the application's.

RETURN VALUES
     The pam_putenv function returns one of the following values:

     [PAM_BUF_ERR]       Memory buffer error.

     [PAM_SYSTEM_ERR]    System error.
