TOASCII(3)						   BSD Library Functions Manual 						TOASCII(3)

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.

     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.

     toascii(int c);

     int
     tolower(int c);

     int
     toupper(int c);

DESCRIPTION

     The above functions perform character tests and conversions on the integer c.  They are available as macros, defined in the include file
     <ctype.h>, or as true functions in the C library.	See the specific manual pages for more information.
