FatVolRdSects()

PROTOTYPE

#include <fsdriver.h>

int FatVolRdSects(FAT *fat, void *buf, ui32 first_sect, int count);

DESCRIPTION

FatVolRdSects() reads count sectors from the FAT volume specified by fat, a handle previously returned by FatVolOpen(), beginning at sector first_sect. buf points to where the data is copied to.

If successful, FatVolRdSects() returns 0. Otherwise, it sets errno and returns -1.

ERROR CODES

EFAULT	Either fat or buf equals NULL.
EINVAL	fat is not a valid volume handle or buf is not aligned.

EXAMPLE

      FAT *fat;
      ui8 buf[512];
