For example you might define a static/internal function within your C program like this:
...
static void vAverage (X_
...
LONG lArg1,
...
X_LONG lArg2,
1
{
X_LONG lAverage;
lAverage = (lArg1 + lArg2) / 2;
...
X_LONG lArg2,
1
{
X_LONG lAverage;
lAverage = (lArg1 + lArg2) / 2;
U_BIF_SET_RET_FROM_
...
LONG (sRetNo,
...
lAverage);
...
return;
return;
}
To execute this function you might code:
...
vAverage (6,
...
42,
...
17);
If you do this you will find that it will not compile.
...
You can correct this problem by changing the code to be like this:
...
static void vAverage (U_BIF_STANDARD_PARAMETERS,
X_LONG lArg1,
X_LONG lArg2,
X_SHORT sRetNo)
{
X_LONG lAverage;
lAverage = (lArg1 + lArg2) / 2;
...
X_LONG lArg1,
X_LONG lArg2,
X_SHORT sRetNo)
{
X_LONG lAverage;
lAverage = (lArg1 + lArg2) / 2;
U_BIF_SET_RET_FROM_
...
LONG (sRetNo,
...
lAverage);
...
return;
return;
}
and then by changing the execution of the function to be like this:
...
vAverage (U_BIF_STANDARD_ARGUMENTS,
...
6,
...
42,
...
17);
Of course the behavior of some U_BIF macros is changed when they are used in a static or internal function.
...
So in this example you could code:
...
vAverage (U_BIF_STANDARD_ARGUMENTS,
...
6,
...
42,
...
17);
U_BIF_HANDLE_FATAL_ERROR
