GOpen
GCLIB_DLL_EXPORTED GReturn GCALL GOpen(GCStringIn address, GCon *g)
Open a connection to a Galil Controller.
GReturn
int GReturn
Every function returns a value of type GReturn. See gclib_errors.h for possible values.
Definition: gclib.h:93
G_SMALL_BUFFER
#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
GCon
void * GCon
Connection handle. Unique for each connection in process. Assigned a non-zero value in GOpen().
Definition: gclib.h:94
main
int main(int argc, char *argv[])
Main function for Commands Example.
Definition: commands_example.cpp:18
e
void e(GReturn rc)
A trivial, C++ style return code check used in Galil's examples and demos.
Definition: examples.h:33
jog
GReturn jog(GCon g)
Puts controller into Jog Mode and accepts user input to adjust the speed.
Definition: jog.cpp:29
error
void error(GCon g, GReturn rc)
An example of error handling and debugging information.
Definition: examples.h:40
pause
int pause()
Pauses console apps for a user key stroke.
