I don't remember if you used the same methods that I did or not. I used
the method from Niese-Petersen <Tenp@cris.com>, and in there is alot of
division by 32 to make sure that the right bits get toggled on the right
ints. This caused problems once I hit bit 31 and above because computers
start counting at 0, and to seperate the vector off to the right int for
fiddling with, I had to change all the code like:
void sprintbitarray(int bitvector[], char *names[], int maxar,
char *result)
{
int nr, teller, found = FALSE;
*result = '\0';
for(teller = 0; teller < maxar && !found; teller++)
for (nr = 0; nr < 32 && !found; nr++) {
if (IS_SET_AR(bitvector, (teller*31)+nr))
if (*names[(teller*32)+nr] != '\n') {
if (*names[(teller*32)+nr] != '\0') {
strcat(result, names[(teller*32)+nr]);
strcat(result, " ");
}
} else {
strcat(result, "UNDEFINED ");
}
if (*names[(teller*32)+nr] == '\n')
found = TRUE;
}
if (!*result)
strcpy(result, "NOBITS ");
}
To the following:
void sprintbitarray(int bitvector[], char *names[], int maxar,
char *result)
{
int nr, teller, found = FALSE;
*result = '\0';
for(teller = 0; teller < maxar && !found; teller++)
for (nr = 0; nr < 31 && !found; nr++) {
if (IS_SET_AR(bitvector, (teller*31)+nr))
if (*names[(teller*31)+nr] != '\n') {
if (*names[(teller*31)+nr] != '\0') {
strcat(result, names[(teller*31)+nr]);
strcat(result, " ");
}
} else {
strcat(result, "UNDEFINED ");
}
if (*names[(teller*31)+nr] == '\n')
found = TRUE;
}
if (!*result)
strcpy(result, "NOBITS ");
}
Notice that the only thing that I changed was the '32's to '31's. Nothing
else needed to be changed. There are several point throughout the code
that need this change in the code and in the header files as well.
If you're using some other system, then perhaps my info will give you some
insight into your particular problem.
Good luck!
