 *  ABSTRACT:
 *
 *	Header file for C run-time library wrapper routines
 *
 *  AUTHORS:
 *
 *	Webb Scales
 *
 *  CREATION DATE:
 *
 *	29 March 1990
 *
 *  MODIFICATION HISTORY:
 *
 *	001	Dave Butenhof	30 March 1990
 *		Use "int" instead of "sigset_t" type.
 *	002	Webb Scales	12 April 1990
 *		Return to sigset_t, and supply a typedef for it on VMS.
 *	003	Webb Scales	27 April 1990
 *		And correct the routine prototype for sigwait to use sigset_t.
 *	004	Dave Butenhof	18 May 1990
 *		move sigwait to new cma_px.h (POSIX emulation).
 *	005	Dave Butenhof	29 June 1990
 *		Add typecasts to the VM macros to correct for not having
 *		mutable types ("void *").
 *	006	Paul Curtin	17 September 1990
 *		Added module to CMALIB, from CMA.
 *	007	Webb Scales	17 September 1990
 *		Corrected macro values, moved errno macro to CMA.H
 *	008	Dave Butenhof	11 October 1990
 *		Remove redundant cma_errno prototype.
 *	009	Paul Curtin	24 January 1991
 *		Removed arguments from wrapper macros, changed the
 *		return values on protos, and removed arguments from protos.
 *		Return values now match `man' pages.
 *	010	Paul Curtin	28 January 1991
 *		Conditionalized wrapper macros on _CMA_NOWRAPPERS_
 *	011	Paul Curtin	06 February 1991
 *		More reworking of return types.
 *	012	Dave Butenhof	19 February 1991
 *		Fix prototypes to work with C++ (hopefully without breaking
 *		anyone else).
 *	013	Paul Curtin	06 June 1991
 *		Removed wrapper protos.
 *	014	Dave Butenhof	19 September 1991
 *		Integrate HPUX CMA5 reverse drop: remove wrappers if
 *		_POSIX_REENTRANT_FUNCTIONS is defined.
 *	015	Dave Butenhof	19 November 1991
 *		Remove direct check for _POSIX_REENTRANT_FUNCTIONS; rely on
 *		_CMA_REENTRANT_CLIB_, since we control that. OSF/1 defines
 *		_POSIX_REENTRANT_FUNCTIONS, but OSF DCE reference port isn't
 *		using libc_r.a.
