_ismbblead, _ismbblead_l
Tests a character to determine whether it is a lead byte of a multibyte character.
int _ismbblead( unsigned int c ); int _ismbblead_l( unsigned int c, _locale_t locale );
Parameters
- c
-
Integer to be tested.
- locale
-
Locale to use.
Multibyte characters consist of a lead byte followed by a trailing byte. Lead bytes are distinguished by being in a particular range for a given character set. For example, in code page 932 only, lead bytes range from 0x81 – 0x9F and 0xE0 – 0xFC.
_ismbblead uses the current locale for locale-dependent behavior. _ismbblead_l is identical except that it uses the locale passed in instead.
