Converts a byte character into a wide character

 #include <stdio.h> #include <wchar.h> wint_t btowc ( int c  ); 

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 );
