prordbc( ) - Read CHARACTER Field

The prordbc( ) function reads the value of a CHARACTER field in a shared buffer.
On successful completion, prordbc( ) returns 0; otherwise, it returns a non-zero value:


prordbc ( pbufnam, fhandle, index, pvar, punknown, varlen,
pactlen )
char *pbufnam;
int fhandle;
int index;
char *pvar;
int *punknown;
int varlen;
int *pactlen;
This input parameter points to the name of the specified shared buffer. You supply the name from your OpenEdge application.
This input parameter is the field handle that profldix( ) returns for the specified field.
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.
This output parameter points to a buffer where prordbc( ) returns the value of the specified CHARACTER field.
This output parameter points to an integer where prordbc( ) returns 1 if the field has the Unknown value (?), and returns 0 otherwise.
This input parameter contains the length of the buffer that pvar specifies.
This output parameter points to an integer where prordbc( ) returns the actual length (in bytes) of the data in the specified CHARACTER field.
