*signal.h - defines signal values and routines

|
|
*Purpose:
|
|
* This file defines the signal values and declares the signal functions.
|
|
* [ANSI/System V]
|
|
*
|
|
*Revision History:
|
|
* 06-03-87 JMB Added MSSDK_ONLY comment on OS/2 related constants
|
|
* 06-08-87 JCR Changed SIG_RRR to SIG_SGE
|
|
* 08-07-87 SKS Signal handlers are now of type "void", not "int"
|
|
* 10/20/87 JCR Removed "MSC40_ONLY" entries and "MSSDK_ONLY" comments
|
|
* 12-11-87 JCR Added "_loadds" functionality
|
|
* 12-18-87 JCR Added _FAR_ to declarations
|
|
* 02-10-88 JCR Cleaned up white space
|
|
* 08-22-88 GJF Modified to also work for the 386 (small model only)
|
|
* 12-06-88 SKS Add _CDECL to SIG_DFL, SIG_IGN, SIG_SGE, SIG_ACK
|
|
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
|
|
* 08-15-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
|
|
* 10-30-89 GJF Fixed copyright
|
|
* 11-02-89 JCR Changed "DLL" to "_DLL"
|
|
* 03-01-90 GJF Added #ifndef _INC_SIGNAL and #include <cruntime.h>
|
|
* stuff. Also, removed some (now) useless preprocessor
|
|
* directives.
|
|
* 03-15-90 GJF Replaced _cdecl with _CALLTYPE1 in #defines and
|
|
* prototypes.
|
|
* 07-27-90 GJF Added definition for SIG_DIE (internal action code,
|
|
* not valid as an argument to signal()).
|
|
* 09-25-90 GJF Added _pxcptinfoptrs stuff.
|
|
* 10-09-90 GJF Added arg type specification (int) to pointer-to-
|
|
* signal-handler-type usages
|
|
* 08-20-91 JCR C++ and ANSI naming
|
|
* 07-17-92 GJF Removed unsupported signals: SIGUSR1, SIGUSR2, SIGUSR3.
|
|
* 08-05-92 GJF Function calling type and variable type macros.
|
|
* 01-21-93 GJF Removed support for C6-386's _cdecl.
