warning

[pe4enka]

Hello,
I am wondering what does this warning actually mean and how can I get rid of it?

warning C4047: '==' : 'int' differs in levels of indirection from 'void *'

This part of code coses the problem. It's looking for the error in the input:

else if (strcmp(str,"LI")==0)
				{	
					if ((fscanf(acc_file,"%d", &x_start) == NULL) || (fscanf(acc_file,"%d", &y_start) == NULL) || 
					(fscanf(acc_file,"%d", &x_finish) == NULL) || (fscanf(acc_file,"%d", &y_finish) == NULL) ||
					(fscanf(acc_file,"%d", &line_colour.red) == NULL) || (fscanf(acc_file,"%d", &line_colour.green) == NULL) || 
					(fscanf(acc_file,"%d", &line_colour.blue) == NULL))
					{
						c=1;
						break;
					}
					DrawLine(x_start, y_start, x_finish, y_finish, line_colour);
				}

Can you post up more of the code?

That can often be a prototype/return type mismatch, where has int return type indicated, and the other is returning void *.

I would prefer the if statement to be like this, also:

if (((fscanf(acc_file,"%d", &x_start)) < 1)), etc. note the doubled parenthesis after &x_start

fscanf() return the number of items stored, which if zero, means an error, and EOF (which is nearly always -1) on end of file.

You're thinking of fgets(), which returns NULL, but fscanf() doesn't.

Thank you very much. That worked for me
