request | Defines the request. Input/Output and type of memory are implicit in the value of request. The following lists the supported request values.
G_UTIL_TIMEOUT Read initial timeout value, as specified in GOpen() via --timeout switch.
memory1 is output and must be a pointer to an unsigned short.
memory2 is ignored, use null.
G_UTIL_TIMEOUT_OVERRIDE See GTimeout(). Write/Read override timeout value.
memory1 is input. If nonnull, value must be a pointer to a short which overrides the timeout. Write G_USE_INITIAL_TIMEOUT to use initial timeout. If null, no write occurs.
memory2 is output. If nonnul, value must be a pointer to a short which will be filled with the current override. G_USE_INITIAL_TIMEOUT indicates initial timeout used. If null, no read occurs. memory2 is processed before 'memory1`.
G_UTIL_VERSION See GVersion(). Returns the library version. A valid connection (g) is not necessary, e.g. g may be null.
memory1 is output, and must be a GCStringOut . Data will be null terminated, even if the data must be truncated to do so.
memory2 is input and must be a pointer to a GSize holding the length of the buffer in memory1 .
G_UTIL_INFO See GInfo(). Returns information about the connection.
memory1 is output and must be a GCStringOut . Data will be null terminated, even if the data must be truncated to do so.
memory2 is input and must be a pointer to a GSize holding the length of the buffer in memory1 .
G_UTIL_SLEEP See GSleep(). Platform-independent sleep. A valid connection (g) is not necessary, i.e. g may be null.
memory1 is input and must be a pointer to an unsigned int, units are milliseconds.
memory2 is ignored, use null.
G_UTIL_ADDRESSES Provides a \n delimited listing of all available IP addresses, PCI addresses, and COM ports. A valid connection (g) is not necessary, i.e. g may be null.
memory1 is output and must be a GCStringOut . Data will be null terminated, even if the data must be truncated to do so.
memory2 is input and must be a pointer to a GSize holding the length of the buffer in memory1 .
G_UTIL_IPREQUEST Listens and returns a \n delimited listing of Galil MAC addresses sending BOOT-P or DHCP requests. The function will listen, and block, for roughly 5 seconds. A valid connection (g) is not necessary, i.e. g may be null.
memory1 is output and must be a GCStringOut . Data will be null terminated, even if the data must be truncated to do so.
memory2 is input and must be a pointer to a GSize holding the length of the buffer in memory1 .
G_UTIL_ASSIGN Provides a method to assign an IP address given a Galil MAC address and optionally a host NIC IP address. A valid connection (g) is not necessary, i.e. g may be null. The address to assign will be pinged to ensure its availability before the assign packet is sent. G_GCLIB_UTILITY_IP_TAKEN will be returned by GUtility() if the ping returns a response.
memory1 is input and must be a pointer to a GCStringIn containing the address that is to be assigned. e.g. "192.168.0.43"
memory2 is input and must be a pointer to a GCStringIn containing a comma-separated list with the controller's MAC address, followed by the IP address of the host's network interface to dispatch the assign packet. e.g. "00:50:4C:20:01:23, 192.168.0.42"
If the host IP is omitted, the assign packet is sent out on all network interfaces. e.g. "00:50:4C:20:01:23"
G_UTIL_GCAPS_KEEPALIVE Provides method for kicking the gcaps server. After a default period of 10 minutes of inactivity, gcaps will disconnect the gclib client. To prevent a disconnect, communicate with the hardware or call G_UTIL_GCAPS_KEEPALIVE within the timeout period to reset the timer. The current interval can be optionally read and overwritten.
memory1 is output. If nonnull, value must be a pointer to a GSIZE which will be filled with the current gcaps timeout, in ms.
memory2 is input. If nonnull, value must be a pointer to a GSIZE which overrides the current gcaps timeout, in ms, for this connection.
G_UTIL_DEVICE_INITIALIZE Provides a method to reinitialize a connection after a reset, e.g. an RS command. Depending on the device type, the appropriate commands will be sent to configure the communication bus for optimal performance.
memory1 is ignored, use null.
memory2 is ignored, use null.
