prordbl() - Read LOGICAL Field

The prordbl() function reads the value of a LOGICAL field in a shared buffer.

On successful completion, prordbl() returns 0; otherwise, it returns a non-zero value:

Syntax

int prordbl ( pbufnam, fhandle, index, pvar, punknown ) char *pbufnam; int fhandle; int index; int *pvar; int *punknown;

pbufnam

This input parameter points to the name of the specified shared buffer. You supply the name from your Progress application.

fhandle

This input parameter is the field handle that profldix() returns for the specified field.

index

This input parameter specifies an index value for an array field. If the field is not an array, you must set the value of index to 0.

pvar

This output parameter points to an integer where prordbl() returns the value of the specified LOGICAL field. The prordl() function returns 1 if the LOGICAL field is TRUE, and 0 otherwise.

-tielpunknown

This output parameter points to an integer where prordbl() returns 1 if the field has the Unknown value (?), and returns 0 otherwise.
