Function _retnl() Foundation

Returns an integer numeric value to Xbase++.

Syntax
BOOL _retnl(XppParamList pList, LONG nIntVal);
Parameters
XppParamList pList
Pointer to the Xbase++ parameter list of the function whose return value is being set.
LONG nIntVal
Numeric return value.
Return

Always returns TRUE.

Description

_retnl() is used to return an integer numeric value. Calling this function does not exit the actual function, but merely sets the return value. After the call an access to other C-API functions except for _conRelease() is not allowed anymore and the function should return immediately.

To insure correct operation, a return value has always to be set. In Xbase++, NIL should be returned for procedures, which are functions without return values.

Examples
/* 
Returns a LONG value as a numeric value 
*/ 
#include <xpppar.h> 

_retnl(<pList>, 42);
