__isascii, iswascii
Visual Studio 2012
Determines whether a particular character is an ASCII character.
int __isascii( int c ); int iswascii( wint_t c );
Each of these routines returns nonzero if c is a particular representation of an ASCII character. __isascii returns a nonzero value if c is an ASCII character (in the range 0x00 – 0x7F). iswascii returns a nonzero value if c is a wide-character representation of an ASCII character. Each of these routines returns 0 if c does not satisfy the test condition.
