Sends bytes from a connected socket.
#include <prio.h> PRInt32 PR_Send( PRFileDesc *fd, const void *buf, PRInt32 amount, PRIntn flags, PRIntervalTime timeout);
The function has the following parameters:
- A pointer to a
PRFileDescobject representing a socket.
- A pointer to a buffer containing the data to be sent.
- The size of
- This obsolete parameter must always be zero.
- A value of type
PRIntervalTimespecifying 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_Send blocks until all bytes are sent, a timeout occurs, or an error occurs.
