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 strips all but the low 7 bits from a letter, including parity or other marker bits.

RETURN VALUES

     The toascii() function always returns a valid ASCII character.

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.

     Extended locale versions of these functions are documented in ctype_l(3).	See xlocale(3) for more information.

     These functions, except for digittoint(), isascii(), ishexnumber(), isideogram(), isnumber(), isphonogram(), isrune(), isspecial() and
     toascii(), conform to ISO/IEC 9899:1990 (``ISO C90'').
