GCLIB_DLL_EXPORTED GReturn GCALL GPublishServer(GCStringIn name, GOption publish, GOption save)
Uses GUtility(), G_UTIL_GCAPS_PUBLISH_SERVER to publish local gcaps server to the local network.
Definition: gclibo.c:189
int GReturn
Every function returns a value of type GReturn. See gclib_errors.h for possible values.
Definition: gclib.h:93
#define G_SMALL_BUFFER
Most reads from Galil are small. This value will easily hold most, e.g. TH, TZ, etc.
Definition: gclib.h:89
void e(GReturn rc)
A trivial, C++ style return code check used in Galil's examples and demos.
Definition: examples.h:33
GReturn message(GCon g)
Demonstrates how to receive messages from the controller and detect differences in Trace and crashed ...
Definition: message.cpp:14
GReturn remote_server(const char *server_name)
Publishes local gcaps server to the network.
