int _ismbclower( unsigned int c ); int _ismbcupper( unsigned int c );
- Character to be tested.
Each of these routines returns a nonzero value if the character satisfies the test condition or 0 if it does not. If c<= 255 and there is a corresponding _ismbb routine (for example, _ismbcalnum corresponds to _ismbbalnum), the result is the return value of the corresponding _ismbb routine.
Each of these functions tests a given multibyte character for a given condition.
|Routine||Test condition||Code page 932 example|
|_ismbclower||Lowercase alphabetic||Returns nonzero if and only if c is a single-byte representation of an ASCII lowercase English letter: 0x61<=c<=0x7A.|
|_ismbcupper||Uppercase alphabetic||Returns nonzero if and only if c is a single-byte representation of an ASCII uppercase English letter: 0x41<=c<=0x5A.|
