Name
btowc
Synopsis
Converts a byte character into a wide character
#include <stdio.h> #include <wchar.h> wint_tbtowc
( intc
);
The btowc()
function
returns the corresponding wide character for its byte character
argument, if possible. A return value of WEOF
indicates that the argument’s value
is EOF
, or that the argument does
not represent a valid byte character representation in the initial
shift state of a multibyte stream.
Example
/* Build a table of wide characters for the first 128 byte values */
wchar_t low_table[128];
for ( int i = 0; i < 128 ; i++ )
low_table[ i ] = (wchar_t)btowc
( i );
