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

int _ismbbgraph (
   unsigned int c 
int _ismbbgraph_l (
   unsigned int c,
   _locale_t locale


  • c
    Integer to be tested.

  • locale
    Locale to use.

Return Value

Returns a nonzero value if the expression:

( _PUNCT | _UPPER | _LOWER | _DIGIT ) || _ismbbkprint

is nonzero for c, or 0 if it is not. _ismbbgraph uses the current locale for any locale-dependent behavior. _ismbbgraph_l is identical except that it uses the locale passed in instead. For more information, see Locale.
