int gp_port_info_list_append ( GPPortInfoList list,
GPPortInfo  info 

Append a portinfo to the port information list.

list a GPPortInfoList
info the info to append
Appends an entry to the list. This function is typically called by an io-driver during gp_port_library_list. If you leave info.name blank, gp_port_info_list_lookup_path will try to match non-existent paths against info.path and - if successfull - will append this entry to the list.

This returns index - number of generic entries, not the correct index.
A non-negative number or a gphoto2 error code
