fsetpos (Continued)
Example:
/* This program opens a file and reads bytes at */
/* several different locations. The fgetpos
/* function notes the 8th byte. 21 bytes are
/* read then 18 bytes are read. Next the
/* fsetpos function is set based on the
/* fgetpos position and the previous 21 bytes
/* are reread.
#include <stdio.h> /* for fgetpos, fread,
int main(void)
{
}
Output:
Bytes read: program opens a file
Bytes read: and reads bytes at
Bytes read: program opens a file
