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 7-bit unsigned char value that fits into the ASCII character set, by clearing the high-order bits.

The value returned is that of the converted character.
