Subject: bug sscanf when match fails ?
Reply-To: pierre AT Eng DOT Sun DOT COM


It seems that sscanf does not stop parsing when a match fails (as it
should). The following shows the bug. This has been tested on v1, but
someone told me it was the same with v2.

#include <stdio.h>

main()
{
    char *test_str = "demo PPL_ID 10";    
    char app_name[40], expstr[20];
    int match;
    int app_id;
    app_name[0]=0;
	expstr[0]=0;

    match = sscanf(test_str, "%s %d %s", 
                  app_name, &app_id, expstr);
    printf("match = %d, app_name = \"%s\", app_id = %d, expstr = \"%s\"\n",
            match, app_name, app_id, expstr);
}

/*
Result on Solaris (correct):
============================

match = 1, app_name = "demo", app_id = 0, expstr = ""


Result on DJGPP (incorrect)
========================

match = 2, app_name = "demo", app_id = 0, expstr = "PPL_ID"
