PR_SendTo¶

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.

Description¶

PR_SendTo sends a specified number of bytes from a socket to the specified destination address. The calling thread blocks until all bytes are sent, a timeout has occurred, or there is an error.
