NAME
     pam_putenv -- set the value of an environment variable

DESCRIPTION
     The pam_putenv function sets a environment variable.  Its semantics are similar to those of putenv(3),
     but it modifies the PAM context's environment 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.

SEE ALSO
