|
|
*Purpose:
|
|
* Test if the character is a whitespace character.
|
|
* Handles MBCS chars correctly.
|
|
*
|
|
* Note: Use test against 0x00FF instead of _ISLEADBYTE
|
|
* to ensure that we don't call SBCS routine with a two-byte
|
|
* value.
|
|
*
|
|
*Entry:
|
|
* unsigned int c = character to test
|
|
*
|
|
*Exit:
|
|
* Returns TRUE if character is whitespace, else FALSE

|

|
|
*Exceptions:
