Attribute system is an interface to operate camcorder. Depending on each attribute, camcorder behaves differently.
Attribute system provides get/set functions. Setting proper attributes, a user can control camcorder as he want. (mm_camcorder_set_attributes())
- Also, a user can comprehend current status of the camcorder, calling getter function(mm_camcorder_get_attributes()).
+ Also, a user can comprehend current status of the camcorder, calling getter function(mm_camcorder_get_attributes()).
Beware, arguments of mm_camcorder_set_attributes() and mm_camcorder_get_attributes() should be finished with 'NULL'.
This is a rule for the variable argument.
