/* int ReturnMathErrAndClear();
|
||
|
|
*
|
||
|
|
* ARGUMENT
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* DESCRIPTION
|
||
|
|
* Sets wGMError to GM_SUCCESS, and returns it's previous value.
|
||
|
|
*
|
||
|
|
* SIDE EFFECTS
|
||
|
|
* Does NOT clear the variable wGMErrFunNum (function number
|
||
|
|
* causing error). This is so that ReturnErrFuncNumAndClear() can
|
||
|
|
* get and clear that one separately. If you want to write your own
|
||
|
|
* functions, or do your own checking, remember that wGMErrFunNum
|
||
|
|
* may contain an error function number, but wGMError could have
|
||
|
|
* been cleared by some previous call to here. Function ClearMathError()
|
||
|
|
* unconditionally clears both and can be found in "gm.h". BE SURE YOU ARE
|
||
|
|
* A SOURCE CODE USER AND KNOW WHAT YOU ARE DOING WITH THESE
|
||
|
|
* VARIABLES, AND HOW THEY ARE AFFECTED BY THE INTERNAL ROUTINES,
|
||
|
|
* BEFORE YOU WRITE YOUR OWN ERROR HANDLER!
|
||
|
|
*
|
||
|
|
* RETURNS
|
||
|
|
* Returns value of wGMError (before settting it to GM_SUCCESS).
|
||
|
|
*
|
||
|
|
* POSSIBLE ERROR CODES
|
||
|
|
*
|
||
|
|
* None.
