TOASCII(3)                  Linux Programmer's Manual                 TOASCII(3)



NAME
       toascii - convert character to ASCII

SYNOPSIS
       #include <ctype.h>

       int toascii(int c);

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

       toascii():
           _XOPEN_SOURCE
               || /* Glibc since 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.

CONFORMING TO
       SVr4, BSD, POSIX.1-2001.  POSIX.1-2008 marks toascii() as obsolete,
       noting that it cannot be used portably in a localized application.

BUGS
       Many people will be unhappy if you use this function.  This function will
       convert accented letters into random characters.
