Re: Strange Behavior when calling a C function by a plpgsql stored prcedure

Default parameters are filled in by the C++ compiler. You must provide
them when calling from a non-C++ program.

Subject: [BUGS] Strange Behavior when calling a C function by a plpgsql
stored prcedure

In some plpgsql method, I call some C function with a optional
parameters.

This is the signature of my function :

extern "C" My_Mem_Macro_Parser_Integer myMethod( int nbFields, int toto
= -1)
{
blablabla .....
return integer;
}

When I call this function with the second parameters, there's no
problems.

But if I call without toto :
plpgsql:

CREATE FUNCTION CallMymethodWithoutToto ( INTEGER -- [IN] nb
Field
)
RETURNS INTEGER AS '
'path2MyLib/MyLib.so', 'myMethod'
LANGUAGE 'C';

Appear a strange Behavior :
I'm explain,
in myC function, I switch the value of toto, try to find "-1".
But I NEVER have "-1".

I this case I always have "8" in toto integer !!!!!!
