6.5 Keywords for Input/Output
The following three keywords are available for setting the input/output attributes of parameters.
• IN: Input
• OUT: Output
• INOUT: Input and output
The following optional keywords can also be attached to the keywords listed above (note,
however, that REF and DESC cannot be used at the same time).
• REF: Passing by reference
• DESC: The parameter is not passed from the client to the server
Each of these keywords, specified with one of the data-type keywords listed in section 6.6, works
as a declaration of the subsequent parameter specification.
6.5.1 IN (Input)
Description:
This keyword defines a parameter as an input to the server function. The parameter is transferred
from the client to the server and is then passed to the server function.
Example:
Specification of a server function
int func(int par);
The function takes par as an input and returns a value of type int.
Definition of the server function
int ret = func([IN DFLT]int par);
