pOutData appears to be a pointer to a pointer or a 2d array of strings, like argv parameter to main() In either event line 5 can not work because strtok() only works with 1d character arrays. pOutData needs to be a pointer that is declared similar to the way you declared pToken

Thanks for the reply
The issue i have is i cannot change pOutData due to it being part of some software we are linking too. So i have to make something work around it...any ideas?
Im really stuck here

I would copy the string into some local buffer because strtok() will replace the ; with null characters, which destroys the original string.
char temp[255]; strcpy(temp,*pOutData); pToke = strtok(temp,","); // rest of program here

mmmm still an issue as
printf ("Results 2nd:%s\n", pOutData[size] );
Based on the above printf, i cannot just do a simple strcpy into temp, due to size being included can i?
printf ("Results 2nd:%s\n", pOutData[size] );

ah it is working, except at the end the program is bombing out
any ideas?
for ( size = 0; size < b2b_data_drill_nNoSelect; size++ )
{
if (size == 1 )
{
strcpy(temp,pOutData[size]);
//printf("Temp = %s\n", temp);
ptoken = strtok(temp, ";" );
while( ptoken != NULL )
{
printf ("Results 2nd:%s\n", pOutData[size] );
printf ("ptoken:%s\n", ptoken );
ptoken = strtok(NULL, ";" );
}
}
}
any ideas?

>>except at the end the program is bombing out
Don't know -- probably something else in your program. Did you declare temp variable big enough to hold all the characters in that string ?
>>if (size == 1 )
Why that condition? Just delete the loop and do it like this, unless of course there is other code within that loop that you haven't posted.
