IDC: 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 Appcall is performed.
