# lrs_set_send_buffer

Buffer Functions

Specifies the buffer to send.

    int lrs_set_send_buffer( char *s_desc, char *buffer, int size );

s_desc | A descriptor identifying a socket.
buffer | A pointer to the buffer containing the data to be sent.
size | The size of the data to send in bytes.

The lrs_set_send_buffer function specifies the buffer to send in the next call to lrs_send. The buffer specified in lrs_set_send_buffer is sent, and not the buffer designated in the lrs_send function.

This function is not recorded during a WinSock session—you manually insert it into your script

## Return Values

Windows Sockets Return Values

## Parameterization

You cannot use standard parameterization for any arguments in this function.

## Example

In the following example, the lrs_set_send_buffer function sets the buffer containing the data for socket2. Note that 10 bytes from Buffer are sent on the socket, and not the buffer referenced by "buf21".

Copy code

    /* Set the buffer value. */
    char *Buffer;
    int Size;
    lrs_receive("socket2", "buf20", LrsLastArg);
    lrs_get_last_received_buffer("socket2", &Buffer, &Size);
    /* Make modifications on the last received buffer. */
    . . .
    lrs_set_send_buffer("socket2", Buffer, 10 );
    lrs_send("socket2","buf21", LrsLastArg );
    lrs_free_buffer(Buffer);
