prordr( ) - Read RECID Variable

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


prordr ( psymnam, index, pvar, punknown )
char *psymnam;
int index;
long *pvar;
int *punknown;
This input parameter points to the name of the specified shared RECID 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 long where prordr( ) returns the value of the specified RECID variable.
This output parameter points to an integer where prordr( ) returns 1 if the variable has the Unknown value (?), and returns 0 otherwise.
