|
|
* 06-17-85 TC rewrote to use new varargs macros to be vprintf
|
|
* 04-13-87 JCR added const to declaration
|

|
|
* 12-11-87 JCR Added "_LOAD_DS" to declaration
|
|
* 05-31-88 PHG Merged DLL and normal versions
|
|
* 06-15-88 JCR Near reference to _iob[] entries; improve REG variables
|
|

|
* <stdarg.h>
|
|
* 10-03-90 GJF New-style function declarator.
|
|
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
|
|
* 09-06-94 CFW Replace MTHREAD with _MT.
|
|
* 02-06-94 CFW assert -> _ASSERTE.
|
|
* 03-07-95 GJF _[un]lock_str macros now take FILE * arg.
