Introduction to camera drivers (camlibs)

Every camlib must implement the following three function groups:

We implement the camlib API functions last in this file because camera_init() must reference all the object member functions and by making camera_init() the last function in this file, we can avoid the need for forward declarations of the object member functions.

Note about "static" functions and exporting symbols

The build system uses libtool to explicitly specify the list of exported symbols. Only the three functions of the camlib API (camera_init(), camera_id(), and camera_abilities()) are exported.

Therefore it doesn't matter whether you declare your other functions static or not - regardless of whether they are object member functions or internal camlib functions.

We do not define the object member functions as static in this template in order to have autogenerated documentation about them.

Definition in file template.c.
