toascii - convert character to ASCII

  #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

*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.

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

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

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