toascii (3)

#include <ctype.h>

int toascii(int c);

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

toascii(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_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.

Multithreading (see pthreads(7))

The toascii() function is thread-safe.

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.
