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 OpenEdge 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.
