hello yet again everyone,
im still working on leftsock and ive come to a problem that i am unsure about.
it involes wrapping "C" routines that have a parameter that is "call by value".
how should i handle this in Euphoria? after i:
c_func( name_, { pass_by_value, pass_by_ref } )
does the value of "pass_by_value" just change or what? i know there was a long
thread about call by value on this list just a short time ago but i did not
read any of it.... perhaps i should check the archive? was anything of this
nature disgust already?
any help would be appreciated.
i know it seems im asking so many stupid question about wrapping stuff but
this is my first attempt at wrapping any routines whatsoever.

Don't try to make things too complicated for yourself.
pass_by_value just means to pass a value ( or a number )
pass_by_ref just means to pass the address ( a pointer ) of some memory
location of data ( which has been allocated ) that is need by the C
function.
In other words you are passing the actual VALUE ( by_value )
or a POINTER ( by_ref ) to some allocated data.

Ya, i know. i was *VERY* confused about C/C++ programming when i wrote that
message. Ive been programming in C/C++ for 3 years and i mixed up all that call
by value and call by reference stuff. shit. i should really pull out the old
C++ book and get some things strait in my head again.
sorry about all that confusion. Thanks for straitening my out Bernie and Wolf!
