fread

#include <stdio.h>

U32 fread  (
    void* buffer,      /* storage buffer for data  */
    U32   size,        /* size of each item        */
    U32   count,       /* number of items to read  */
    FILE* stream);     /* file stream to read from */

The function fread reads a number of items with a given size from a data stream to a buffer. The parameter buffer is a void pointer to a buffer to store the items read. The parameter size defines the item size in bytes. The parameter count defines the number of items to read. The parameter stream is a file pointer defining the data stream to read.

The function is included in the library RL-FlashFS. The prototype is defined in the file stdio.h.

• number of items read - on success. This number could be smaller than count if an error occurred or the end-of-file condition was reached.

Note

• The file position indicator is undefined when errors occurred.
