NAME
toascii -- convert a byte to 7-bit ASCII LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <ctype.h> int toascii(int c); DESCRIPTION
The toascii() function returns the argument with all but the lower 7 bits cleared. RETURN VALUES
The toascii() function always returns a valid ASCII character. The result is a non-negative integer in the range from 0 to 127, inclusive. SEE ALSO
ctype(3), isalnum(3), isalpha(3), isascii(3), iscntrl(3), isdigit(3), isgraph(3), islower(3), isprint(3), ispunct(3), isspace(3), isupper(3), isxdigit(3), stdio(3), tolower(3), toupper(3), ascii(7) STANDARDS
The toascii() function conforms to X/Open Portability Guide Issue 4 (``XPG4'') and IEEE Std 1003.1-2001 (``POSIX.1''). The IEEE Std 1003.1-2008 (``POSIX.1'') revision however marked it as obsolete, noting that toascii() cannot be used portably in a localized application. BSD
