Provides a list of all Galil controllers requesting IP addresses via BOOT-P or DHCP.

Parameters:

	requests	The buffer to hold the list of requesting controllers. Data will be null terminated, even if the data must be truncated to do so.
	requests_len	The length of the requests buffer.

Returns:: The success status or error code of the function. See gclib_errors.h for possible values.

GIpRequests() will block about 5 seconds while listening for requests.

Note:: Linux/OS X users must be root to use GIpRequests() and have UDP access to bind and listen on port 67.

 {.cpp}
  //example of listening for controllers needing IP addresses
  GIpRequests(listen_buf, sizeof(listen_buf));
  cout << listen_buf << '\n';

Each line of the returned data will be of the form *model, serial_number, mac*.
