PR_Send¶

Sends bytes from a connected socket.

Syntax¶

#include <prio.h>

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

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.
timeout: A value of type PRIntervalTime specifying the time limit for completion of the receive operation.

The function returns one of the following values:

A positive number indicates the number of bytes successfully sent. If the parameter fd is a blocking socket, this number must always equal amount.
The value -1 indicates a failure. The reason for the failure can be obtained by calling PR_GetError.

PR_Send blocks until all bytes are sent, a timeout occurs, or an error occurs.
