int fgetpos ( FILE * stream, fpos_t * position );

<cstdio>

Get current position in stream

Gets the information needed to uniquely identify the current value of the stream's position indicator and stores it in the location pointed by position.
The parameter position should point to an already allocated object of the type fpos_t, which is only intended to be used as a paremeter in future calls to fsetpos.
To retrieve the value of the internal file position indicator as an integer value, use ftell function instead.

Parameters

stream

Pointer to a FILE object that identifies the stream.

position

Pointer to a fpos_t object.

Return Value

Example

/* fgetpos example */
#include <stdio.h>
int main ()
{
   FILE * pFile;
   int c;
   int n;
   fpos_t pos;

   pFile = fopen ("myfile.txt","r");
   if (pFile==NULL) perror ("Error opening file");
   else
   {
     c = fgetc (pFile);
     printf ("1st character is %c\n",c);
     fgetpos (pFile,&pos);
     for (n=0;n<3;n++)
     {
        fsetpos (pFile,&pos);
        c = fgetc (pFile);
        printf ("2nd character is %c\n",c);
     }
     fclose (pFile);
   }
   return 0;
}
