Hy all!
I'm trying to build a function that will have 2 pointers as parameters.
When this function is called by the main function, is should modify the 2nd
parameter and the main function should be able to work with the second
parameter modified. But, inside the function that work with the pointers,
everything works well, but, when the second function exits, the pointer of
main functions hasn't changed. Look the code below:
void ForwardColumnsOnRecord(Char *LastColumn, Char *DestColumn, UInt16
NumColsToAdvance)
{
int Count;
int NumChars=0;
DestColumn = LastColumn;
for (Count = 0; Count < NumColsToAdvance; Count++)
{
NumChars = NumChars + StrLen(DestColumn) + 1;
DestColumn = LastColumn + NumChars;
}
return;
}
dbPtrF = NULL;
OpenDatabase(&dbPtrF, "SAF_CLIENTES");
{
MemHandle h;
Char *Codigo, *Razao;
h = DmQueryRecord(dbPtrF, SelectedClientIDX);
Codigo = (Char *) MemHandleLock(h);
ForwardColumnsOnRecord(Codigo, Razao, 1); // here, the pointer Razao
shoud assume the value that DestColumn assumed inside the code, but it,s not
working.
}
DmCloseDatabase(dbPtrF);
Thanks all, and sorry by the idiot question!
