*wrt2err.c - write an LSTRING to stderr (OS/2 version)

|
||
|
|
*
|
||
|
|
*Purpose:
|
||
|
|
* This module contains a routine __wrt2err that writes an LSTRING
|
||
|
|
* (one byte length followed by the several bytes of the string)
|
||
|
|
* to the standard error handle (2). This is a helper routine used
|
||
|
|
* for MATH error messages (and also FORTRAN error messages). It
|
||
|
|
* is in the C library rather than the math library because there
|
||
|
|
* are separate MS-DOS and MS OS/2 versions.
|
||
|
|
*
|
||
|
|
*Revision History:
|
||
|
|
* 06-30-89 PHG module created, based on asm version
|
||
|
|
* 03-16-90 GJF Made calling type _CALLTYPE1, added #include
|
||
|
|
* <cruntime.h> and fixed the copyright. Also, cleaned
|
||
|
|
* up the formatting a bit.
|
||
|
|
* 07-24-90 SBM Removed '32' from API names
|
||
|
|
* 10-04-90 GJF New-style function declarator.
|
||
|
|
* 12-04-90 SRW Changed to include <oscalls.h> instead of <doscalls.h>
|
||
|
|
* 04-26-91 SRW Removed level 3 warnings
|
||
|
|
* 07-18-91 GJF Replaced call to DbgPrint with WriteFile to standard
|
||
|
|
* error handle [_WIN32_].

*__wrt2err(msg) - write an LSTRING to stderr
|
||
|
|
*
|
||
|
|
*Purpose:
|
||
|
|
* Takes a near pointer in BX, which is a pointer to an LSTRING which
|
||
|
|
* is to be written to standard error. An LSTRING is a one-byte length
|
||
|
|
* followed by that many bytes for the character string (as opposed to
|
||
|
|
* a null-terminated string).
|
||
|
|
*
|
||
|
|
*Entry:
|
||
|
|
* char *msg = pointer to LSTRING to write to standard error.
|
||
|
|
*
|
||
|
|
*Exit:
|
||
|
|
* Nothing returned.
|
||
|
|
*
|
||
|
|
*Exceptions:
|
||
|
|
* None handled.
