GReturn record_position(GCon g, char *fileA, char *fileB)
Record user's training and saves to a text file.
void * GCon
Connection handle. Unique for each connection in process. Assigned a non-zero value in GOpen().
Definition: gclib.h:92
GCLIB_DLL_EXPORTED GReturn GCALL GUtility(GCon g, GOption request, GMemory memory1, GMemory memory2)
Provides read/write access to driver settings and convenience features based on the request variable.
int main(int argc, char *argv[])
Main function for Commands Example.
#define G_UTIL_ERROR_CONTEXT
GUtility(), provides additional error context, where available.
Definition: gclib.h:70
GCLIB_DLL_EXPORTED GReturn GCALL GOpen(GCStringIn address, GCon *g)
Open a connection to a Galil Controller.
GCLIB_DLL_EXPORTED void GCALL GError(GReturn rc, GCStringOut error, GSize error_len)
Provides a human-readable description string for return codes.
Definition: gclibo.c:459
unsigned int GSize
Size of buffers, etc.
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:87
void e(GReturn rc)
A trivial, C++ style return code check used in Galil's examples and demos.
Definition: examples.h:30
int GReturn
Every function returns a value of type GReturn. See gclib_errors.h for possible values.
Definition: gclib.h:91
