tftpc_fread

#include <net_config.h>

U16 tftpc_fread (
    FILE* file,     /* Pointer to the file to read from. */
    U8*   buf,      /* Pointer to buffer, to store the data. */
    U16   len );    /* Number of bytes to read. */

The tftpc_fread reads len bytes from the local file identified by the file stream pointer in the function argument. The argument buf is a pointer to the buffer where the function stores the read data.

The tftpc_fread function is in the TFTPC_uif.c module. The prototype is defined in net_config.h.

note

• The tftpc_fread function must read len bytes. The TFTP Client stops reading and closes the TFTP session, if the return value is less than len bytes.
• This is an interface function of TFTP Client.

The tftpc_fread function returns the number of bytes read from the file.

tftpc_fclose, tftpc_fopen, tftpc_fwrite

U16 tftpc_fread (void *file, U8 *buf, U16 len) {
  /* Read 'len' bytes from file to buffer 'buf'. Return number of bytes */
  /* copied. The file will be closed, when the return value is < 'len'  */
  return (fread (buf, 1, len, file));
