The tool can then attach to a targetserver using a call to <b><i><a href="./wtx.html#wtxToolAttach">wtxToolAttach</a></i>( )</b>. Each WTX handle can only beconnected to one server at a time. After a successful call of<b><i><a href="./wtx.html#wtxToolAttach">wtxToolAttach</a></i>( )</b>, the handle is considered bound to the specified targetserver until a call of <b><i><a href="./wtx.html#wtxToolDetach">wtxToolDetach</a></i>( )</b> is made; then the handle can be attached to a new target server. When thehandle is no longer required, call <b><i><a href="./wtx.html#wtxTerminate">wtxTerminate</a></i>( )</b> to release anyinternal storage used by the handle. The handle must not be used after<b><i><a href="./wtx.html#wtxTerminate">wtxTerminate</a></i>( )</b> has been called.<p><pre>#include "wtx.h" HWTX hWtx; /* initialize WTX session handle */ if (wtxInitialize (&hWtx) != WTX_OK) return (WTX_ERROR); /* attach to Target Server named "soubirou" */ if (wtxToolAttach (hWtx, "soubirou", "wtxApp") != WTX_OK) return (WTX_ERROR); /* register for events we want to hear about (all events here) */ if (wtxRegisterForEvent (hWtx, ".*") != WTX_OK) { wtxToolDetach (hWtx); return (WTX_ERROR); } /* core of the WTX application */ . . . . /* detach form the Target Server */ wtxToolDetach (hWtx); /* terminate WTX session */ wtxTerminate (hWtx);</pre>Most WTX calls return either a pointer value which is NULL on error or aSTATUS value which is <b>WTX_ERROR</b> if an error occurs. A descriptive stringcan be obtained for the last error that occurred by calling<b><i><a href="./wtx.html#wtxErrMsgGet">wtxErrMsgGet</a></i>( )</b>.<p>Note that virtually all WTX calls can fail due to an error in the messagetransport layer used to carry out WTX requests. Transport errors thatare non-recoverable result in the tool being detached from the serverand an error code of <b>WTX_ERR_API_TOOL_DISCONNECTED</b>. If a non-fatalerror occurs, <b>WTX_ERR_API_REQUEST_FAILED</b> is set, except in the case ofa timeout. In that case the error is <b>WTX_ERR_API_REQUEST_TIMED_OUT</b>. Inthe non-fatal cases, the call may be retried. In the fatal case, retrying thecall results in the error <b>WTX_ERR_API_NOT_CONNECTED</b>.<p>All API calls attempt to check the validity of the API handle provided.The error <b>WTX_ERR_API_INVALID_HANDLE</b> indicates a bad handle. Otherpointer arguments are checked and <b>WTX_ERR_API_INVALID_ARG</b> indicates abad argument value such as a NULL pointer. API calls that require thehandle to be connected to a target server generate the<b>WTX_ERR_API_NOT_CONNECTED</b> error if the handle is not connected.<p>In addition to simple error return values, the C API allows errorhandlers to be installed on a per handle basis using<b><i><a href="./wtx.html#wtxErrHandlerAdd">wtxErrHandlerAdd</a></i>( )</b>. If an error occurs, the last installedhandler is called first. If it returns a TRUE value, then anypreviously installed handlers are called in reverse order, in other words,last installed, first called. The C API includes macros that use thepredefined error handler <b><i><a href="./wtx.html#wtxErrExceptionFunc">wtxErrExceptionFunc</a></i>( )</b> to support C++ styleexception catching. Once an API handle has been initialized using<b><i>wtxInitiliaze</i>( )</b>, it can be used in the <b>WTX_TRY</b> macro to cause APIerrors to be treated like exceptions. When this is done, an API callthat would normally return an error code actually causes a jumpstraight to the nearest <b>catch</b> handler as specified using a <b>WTX_CATCH</b>or <b>WTX_CATCH_ALL</b> macro. The previous example is shown below using thisstyle of error handling.<p><pre>#include "wtx.h" HWTX hWtx; /* initialize WTX session handle */ if (wtxInitialize (&hWtx) != WTX_OK) return (WTX_ERROR); /* Start a block in which errors will be "caught" by a catch block */ WTX_TRY (hWtx) { /* attach to Target Server named "soubirou" */ wtxToolAttach (hWtx, "soubirou", "wtxApp"); /* register for events we want to hear about (all events here) */ wtxRegisterForEvent (hWtx, ".*"); /* core of the WTX application */ . . . . /* detach form the Target Server */ wtxToolDetach (hWtx); } /* Catch a specific error, WTX_ERR_API_NOT_CONNECTED */ WTX_CATCH (hWtx, WTX_ERR_API_NOT_CONNECTED) { fprintf (stderr, "Connection lost, exiting\n"); wtxTerminate (hWtx); exit (0);⌨️ 快捷键说明
