I've made sample patch + speed up for wide output to file for 'ls'
conversion specifications (only one call to __ms_fwprintf function).
Now works extended sample:
#define __USE_MINGW_ANSI_STDIO 1
#include <stdlib.h>
#include <stdio.h>
#include <fcntl.h>
int main( void )
{
char *nonTerminated = malloc (1);
wchar_t *nonTerminatedW = malloc (2);
nonTerminated[0] = 'a';
nonTerminatedW[0] = 'b';
printf ("%.1s\n", nonTerminated);
printf ("%.1ls\n", nonTerminatedW);
wprintf (L"%.1s\n", nonTerminated);
wprintf (L"%.1ls\n", nonTerminatedW);
_setmode(_fileno(stdout), _O_U8TEXT);
wprintf(L"%8.1ls%-33ls%lc", nonTerminatedW, L" and TerminatedW", '!');
free (nonTerminated);
free (nonTerminatedW);
return 0;
}
W dniu 2016-05-02 o 19:50, Hannes Domani pisze:
In this example any of the (w)printf()'s now call strlen()/wcslen(), even
though the precision is limited to 1 character:
#define __USE_MINGW_ANSI_STDIO 1
#include <stdlib.h>
#include <stdio.h>
int main( void )
{
char *nonTerminated = malloc (1);
wchar_t *nonTerminatedW = malloc (2);
nonTerminated[0] = 'a';
nonTerminatedW[0] = 'b';
printf ("%.1s\n", nonTerminated);
printf ("%.1ls\n", nonTerminatedW);
wprintf (L"%.1s\n", nonTerminated);
wprintf (L"%.1ls\n", nonTerminatedW);
free (nonTerminated);
free (nonTerminatedW);
return 0;
}
