LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <ctype.h>

     int
     toascii(int c);


DESCRIPTION

     The toascii() function returns the argument with all but the lower 7 bits
     cleared.


RETURN VALUES

     The toascii() function always returns a valid ASCII character.  The
     result is a non-negative integer in the range from 0 to 127, inclusive.

STANDARDS

     The toascii() function conforms to X/Open Portability Guide Issue 4
     (``XPG4'') and IEEE Std 1003.1-2001 (``POSIX.1'').  The IEEE Std
     1003.1-2008 (``POSIX.1'') revision however marked it as obsolete, noting
     that toascii() cannot be used portably in a localized application.
