Functions

An IDC function always returns a value. There are 2 kinds of functions:

• built-in functions

• user-defined functions A user-defined function is declared this way: static func(arg1,arg2,arg3) { statements ... } It is not necessary to specify the parameter types because all necessary type conversions are performed automatically.

By default all function arguments are passed by value, except:

  - objects are always passed by reference
  - functions are always passed by reference
  - it is possible to pass a variable by reference using the & operator

If the function to call does not exist, IDA tries to resolve the name using the debugged program labels. If it succeeds, an dbg_appcall is performed.
