NAME
       cuserid() - get character login name of the user

SYNOPSIS
   Remarks:
       Because	this  function	behaved differently in previous releases of HP-UX, and behaves differently on other systems, its use is not recom-
       mended.	It is provided only for conformance to current industry standards, and is subject to withdrawal in future releases of HP-UX.

       For portability and security, application writers and maintainers should search their existing code and replace references to with  equiva-
       lent calls to or depending on which user name is desired.

DESCRIPTION
       generates  a  character-string  representation  of  the	user  name  corresponding to the effective user ID of the process.  If s is a NULL
       pointer, this representation is generated in an internal static area, the address of which is returned.	Otherwise, s is assumed  to  point
       to an array of at least characters; the representation is left in this array.  The constant is defined in the header file.

       For multi-thread applications, if s is a NULL pointer, the operation is not performed and a NULL pointer is returned.

DIAGNOSTICS
       If the login name cannot be found, returns a NULL pointer; if s is not a NULL pointer, a null character is placed at s[0].

WARNINGS
   Obsolescent Interfaces
       is to be obsoleted at a future date.
