_ismbclegal, _ismbclegal_l, _ismbcsymbol, _ismbcsymbol_l

Checks whether a multibyte character is a legal or symbol character.

Important note Important

This API cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported with /ZW.

int _ismbclegal(
   unsigned int c 
);
int _ismbclegal_l(
   unsigned int c, 
   _locale_t locale
);
int _ismbcsymbol(
   unsigned int c 
);
int _ismbcsymbol_l(
   unsigned int c,
   _locale_t locale
);

c

Character to be tested.

locale

Locale to use.

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.

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

_ismbclegal

Valid multibyte

Returns nonzero if and only if the first byte of c is within ranges 0x81 – 0x9F or 0xE0 – 0xFC, while the second byte is within ranges 0x40 - 0x7E or 0x80 - FC.

_ismbcsymbol

Multibyte symbol

Returns nonzero if and only if 0x8141<=c<=0x81AC.
