_ismbclower, _ismbclower_l, _ismbcupper, _ismbcupper_l

Visual Studio 2008

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
);

Parameters

c: Character to be tested.
locale: Locale to use.

Return Value

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.

Remarks

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.
