GCLIB_DLL_EXPORTED GReturn GCALL GOpen(GCStringIn address, GCon *g)
Open a connection to a Galil Controller.
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 * GCon
Connection handle. Unique for each connection in process. Assigned a non-zero value in GOpen().
Definition: gclib.h:94
int main(int argc, char *argv[])
Main function for Commands Example.
void e(GReturn rc)
A trivial, C++ style return code check used in Galil's examples and demos.
Definition: examples.h:33
GReturn motion_complete(GCon g)
Uses interrupts to track when the motion of controller is completed.
void error(GCon g, GReturn rc)
An example of error handling and debugging information.
Definition: examples.h:40
int pause()
Pauses console apps for a user key stroke.
Definition: examples.h:62
