Sends bytes a socket to a specified destination.

Syntax

#include <prio.h> 

PRInt32 PR_SendTo(
  PRFileDesc *fd, 
  const void *buf,
  PRInt32 amount, 
  PRIntn flags, 
  const PRNetAddr *addr, 
  PRIntervalTime timeout);

Parameters

The function has the following parameters:

fd
A pointer to a PRFileDesc object representing a socket.
buf
A pointer to a buffer containing the data to be sent.
amount
The size of buf (in bytes).
flags
This obsolete parameter must always be zero.
addr
A pointer to the address of the destination.
timeout
A value of type PRIntervalTime specifying the time limit for completion of the receive operation.

Returns

The function returns one of the following values:

  • A positive number indicates the number of bytes successfully sent.
  • The value -1 indicates a failure. The reason for the failure can be obtained by calling PR_GetError.
