/* int ReturnErrFuncNumAndClear()
|
||
|
|
*
|
||
|
|
* ARGUMENT
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* DESCRIPTION
|
||
|
|
* Sets wGMFunErrNum to 0, and returns it's previous value.
|
||
|
|
*
|
||
|
|
* SIDE EFFECTS
|
||
|
|
* Does NOT clear the variable wGMError (global error number).
|
||
|
|
* See ReturnMathErrAndClear() for that discussion. If you want to
|
||
|
|
* write your own functions, or do your own checking, remember that
|
||
|
|
* wGMFunErrNum may contain an error function number, but wGMError could
|
||
|
|
* have been cleared by some previous call to ReturnMathErrAndClear().
|
||
|
|
* 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 EFFECTED BY THE INTERNAL
|
||
|
|
* ROUTINES, BEFORE YOU WRITE YOUR OWN ERROR HANDLER!
|
||
|
|
*
|
||
|
|
* RETURNS
|
||
|
|
* Returns value of wGMFunErrNum.
|
||
|
|
*
|
||
|
|
* POSSIBLE ERROR CODES
|
||
|
|
*
|
||
|
|
* None.
