WSTransferToEndOfLoopbackLink (C Function)

int WSTransferToEndOfLoopbackLink(WSLINK d,WSLINK s)

transfers the full contents of the loopback link s to the destination link d.

Details

  • s and d should be distinct.
  • s must be a loopback link, while d may be a loopback link or an ordinary link.
  • WSTransferToEndOfLoopbackLink() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • WSTransferToEndOfLoopbackLink() is declared in the WSTP header file wstp.h.

Examples

Basic Examples  (1)

#include "wstp.h"

/* build up an expression on a loopback link and send that expression to a second link */

void f(WSLINK lp1, WSLINK lp2)
{
    if(! WSPutFunction(lp1, "EvaluatePacket", 1))
        { /* unable to put the function to lp1 */ }

    if(! WSPutFunction(lp1, "ToExpression", 1))
        { /* unable to put the function to lp1 */ }

    if(! WSPutString(lp1, "a = Table[Random[Integer, 11],{12}];", 36))
        { /* unable to put the string to lp1 */ }

    if(! WSEndPacket(lp1))
        { /* unable to send the end-of-packet indicator to lp1 */ }

    if(! WSFlush(lp1))
        { /* unable to flush any outgoing data buffered in lp1 */ }

    if(! WSTransferToEndOfLoopbackLink(lp2, lp1))
        { /* unable to transfer all the data from lp1 to lp2 */ }
