prordl( ) - Read LOGICAL Variable

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


prordl ( psymnam, index, pvar, punknown )
char *psymnam;
int index;
int *pvar;
int *punknown;
This input parameter points to the name of the specified shared LOGICAL 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 prordl( ) returns the value of the specified LOGICAL variable. The prordbl( ) function returns 1 if the LOGICAL variable is TRUE, and 0 otherwise.
This output parameter points to an integer where prordl( ) returns 1 if the variable has the Unknown value (?), and returns 0 otherwise.
