To aid the work of the application developer a library of miscellaneous functions is provided. It is called libpam_misc, and contains a text based conversation function, and routines for enhancing the standard PAM-environment variable support.

The functions, structures and macros, made available by this library can be defined by including <security/pam_misc.h>. It should be noted that this library is specific to Linux-PAM and is not referred to in the defining DCE-RFC (see See also) below.
