Returning user-defined types with user-defined functions

[Gintaras]

A function can return only types of size 1, 2, 4, 8, 16. To return an user-defined type, use reference argument.

This function returns copy of JobSystem.JobArray[iLoop]:

Code:

Copy      Help

function int'iJobNr tJobArrayElement&retVal
int iLoop

for iLoop 0 JobSystem.JobArray.len
,if(iJobNr = JobSystem.JobArray[iLoop].nr)
,,break
;;;end-for
retVal=JobSystem.JobArray[iLoop]

Calling:

Code:

Copy      Help

tJobArrayElement je
Func(1 je)
;;;now, manipulating je does not affect JobSystem.JobArray[iLoop]


----

This function returns address of JobSystem.JobArray[iLoop]:

Code:

Copy      Help

function'tJobArrayElement* int'iJobNr
int iLoop

for iLoop 0 JobSystem.JobArray.len
,if(iJobNr = JobSystem.JobArray[iLoop].nr)
,,break
;;;end-for
ret &JobSystem.JobArray[iLoop]

Calling:

Code:

Copy      Help

tJobArrayElement& r=Func(1)
;now, when you manipulate r, you actually manipulate JobSystem.JobArray[iLoop]


Of course, you could not return pointer to local variable.
