Convert a multibyte character into a wide character
#include <stdlib.h> int mbtowc( wchar_t *pwc, const char *s, size_t n );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The mbtowc() function converts a single multibyte character pointed to by s into a wide-character code pointed to by pwc, to a maximum of n bytes. The function stops early if it encounters the NULL character.
This function is affected by LC_CTYPE.
The mbrtowc() function is a restartable version of mbtowc().
#include <stdio.h> #include <stdlib.h> int main( void ) { char *wc = "string"; wchar_t wbuffer[10]; int i, len; printf( "State-dependent encoding? " ); if( mbtowc( wbuffer, NULL, 0 ) ) { printf( "Yes\n" ); } else { printf( "No\n" ); } len = mbtowc( wbuffer, wc, 2 ); wbuffer[len] = '\0'; printf( "%s(%d)\n", wc, len ); for( i = 0; i < len; i++ ) { printf( "/%4.4x", wbuffer[i] ); } printf( "\n" ); return EXIT_SUCCESS; }
This produces the output:
State-dependent encoding? No string(1) /0073
