Determines whether a byte is a trailing byte of a multibyte character.

int _ismbbtrail(  
   unsigned int c   
int _ismbbtrail_l(  
   unsigned int c,  
   _locale_t locale   


The integer to be tested.

The locale to use.

_ismbbtrail returns a nonzero value if the integer c is the second byte of a multibyte character. For example, in code page 932 only, valid ranges are 0x40 to 0x7E and 0x80 to 0xFC.

_ismbbtrail uses the current locale for locale-dependent behavior. _ismbbtrail_l is identical except that it uses the locale that's passed in instead. For more information, see Locale.
