Segmentation fault when passing file pointer

[Brendan Wing]

Howdy,

I was trying pass a file pointer from main to another function, so i can use the same file stream to perform certain task instead of closing stream on main then open a new one on the called function.

the code basically looks like this:

int func(FILE* pfile) {
   //whatever task i need to perform
 
}
 
int main(){
 
   FILE* pfile;
   pfile = fopen("filename", "f+");
   while(feof(pfile) == 0){
      //Print what's in the file
   }
 
   func(pfile);
 
}

But when func is called, it gives me segmentation fault.
Am i doing something i'm not suppose to?

Thanks!

THis code:

while(feof(pfile) == 0){
 //Print what's in the file
 }
 etc...

says to go into the loop only if the file is at end of file.

Maybe you could try:

while(feof(pfile) != 0){
 //Print what's in the file
 }
