_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
);

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.
