NAME

       toascii - convert character to ASCII

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <ctype.h>

       [[deprecated]] int toascii(int c);

   Feature Test Macro Requirements for glibc (see
   feature_test_macros(7)):

       toascii():
           _XOPEN_SOURCE
               || /* glibc >= 2.19: */ _DEFAULT_SOURCE
               || /* glibc <= 2.19: */ _SVID_SOURCE || _BSD_SOURCE

DESCRIPTION

       toascii() converts c to a 7-bit unsigned char value that fits
       into the ASCII character set, by clearing the high-order bits.

RETURN VALUE

       The value returned is that of the converted character.
