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
main
int main(int argc, char *argv[])
Main function for Commands Example.
Definition: commands_example.cpp:18
ip_assigner
GReturn ip_assigner(char *serial_num, int address)
Assigns controller an IP Adress given a serial number and a 1 byte address.
Definition: ip_assigner.cpp:26
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.
