prordi( ) - Read INTEGER Variable

The prordi( ) function reads the value of a shared INTEGER variable.
On successful completion, prodi( ) returns 0; otherwise, it returns a non-zero value:


prordi ( psymnam, index, pvar, punknown )
char *psymnam;
int index;
long *pvar;
int *punknown;
This input parameter points to the name of the specified shared INTEGER variable. You supply the name from your OpenEdge application.
This input parameter specifies an index value for an array variable. If the variable is not an array, you must set the value of index to 0.
This output parameter points to a buffer where prordi( ) returns the value of the specified INTEGER variable.
This output parameter points to an integer where prordi( ) returns 1 if the variable has the Unknown value (?), and returns 0 otherwise.
