                                   by value enum-flags
                                   by reference number-of-printers-found

Parameters

enum-handle: Call prototype (see Key): cblt-pointer; Picture: pointer.
enum-flags: Call prototype (see Key): cblt_os_flags; Picture: pic x(4) comp-5 or pic x(8) comp-5 (64-bit native only).
number-of-printers-found: Call prototype (see Key): cblt_os_size; Picture: pic x(4) comp-5 or pic x(8) comp-5 (64-bit native only).

On Entry:

enum-handle: Not set.
enum-flags: Flags controlling the behavior of the call. Must be set to 0.
number-of-printers-found: Not set.

On Exit:

enum-handle

Valid enumeration handle if number of printers > 0

number-of-printers-found

Number of printers found

return-value

One of:

0: Enumeration started
!= 0: PC_PRINTER error code
