toascii - convert character to ASCII

Standard C library (libc,~-lc)

#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

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

The value returned is that of the converted character.

For an explanation of the terms used in this section, see attributes(7).
