_ismbclower, _ismbclower_l, _ismbcupper, _ismbcupper_l
Checks whether a multibyte character is a lowercase or uppercase character.
int _ismbclower( unsigned int c ); int _ismbclower_l( unsigned int c, _locale_t locale ); int _ismbcupper( unsigned int c ); int _ismbcupper_l( unsigned int c, _locale_t locale );
Each of these functions tests a given multibyte character for a given condition.
The versions of these functions with the _l suffix are identical except that they use the locale passed in instead of the current locale for their locale-dependent behavior. For more information, see Locale.
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. |
_ismbclower_l | 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. |
_ismbcupper_l | Uppercase alphabetic | Returns nonzero if and only if c is a single-byte representation of an ASCII uppercase English letter: 0x41<=c<=0x5A. |
