Timing out a WTC call

Question

Hi
I am making an outbound WTC call to a webservice from my tuxedo service.
Is there a way I can set a timeout to this specific call so that if this WTC call is responding after specific time, I can continue with my flow in the tuxedo service.
I am assuming that BLOCK TIME is used to the tuxedo service as a whole. But this could impact my other flows where I am OK to wait for more time.
Basically below should be the flow of tuxedo service
tuxservice01
status = tpcall("wtcWebService01", (char *)pInpRec,0, (char **)&pOutBuf, &olen, FLAG ); /* Not sure about the flag to be used in this case */
if(status != 0)
if(tperrno == TIMEOUT)
handle timeout
goto nextstep
nextstep
Thanks

Hi Raj,
Depending upon the version of Tuxedo you are using, you may be able to set BLOCKTIME on a per call, per context, or per service basis. Starting with Tuxedo 9.0, the time to wait on a blocking call can be set either in the *SERVICES section of the UBBCONFIG file, or using the tpsblktime() function to set it on a per call or per context basis.  Please note that timing out a request with BLOCKTIME doesn't abort the request, i.e., the request will still likely be processed, although that depends upon a number of factors.  BLOCKTIME simply limits the amount of time a blocking call will wait to be unblocked.
