intppty
set interface argument passing properties
Syntax
funs=intppty() intppty(fun) intppty(fun, action)
Arguments
- fun
string, module name (see getmodules)
- action
string, action to realize, value should be "add" or "remove"
- funs
string vector, vector of module names (see getmodules)
Description
The interface programs may be written in 2 different ways for the mode of function argument passing.
In the first and default way, the arguments are passed by value. With the following syntax:
foo(A,1+2)
the argument associated with A will be passed by value (a copy
of A is made before foo is called), and
the argument associated with 1+2 will be passed by value.
In the second way arguments may be passed be reference if there are "named arguments" (no copy of the variable value is done). With the following syntax:
foo(A,1+2)
the argument associated with A will be passed by reference, and
the argument associated with 1+2 will be passed by value.
 | Warning: declaring that the interface with number
fun can handle arguments passed by reference if it is not the
case should produce unpredictable results. |
intppty(fun, "remove") suppress this property
for the interface fun.
intppty() returns the vector of interfaces which handle
arguments passed by reference.
This function may be useful for dynamically loaded interface (see addinter).
