PPCAcceptSync

Indicate willingness to accept incoming session request

#include <PPCToolbox.h> PPC Toolbox

PPCAcceptPBPtr pb; Pointer to PPC parameter block

Boolean async; if TRUE, use asynchronous communications

returns Error Code; 0=no error

On entry A0: pointer to a parameter block

D0: selector (4)

On exit D0: result code

Parameter block

Æ 12 ioCompletion long address of a completion routine

¨ 16 ioResult short result code

Æ 40 sessRefNum long session reference number of session to accept

Use the PPCAccept function to indicate that an application is willing to

accept an incoming session request after a PPCInform function completes.

If your application calls this function asynchronously, you must specify in

the ioCompletion field either the address of a completion routine or NIL. If

ioCompletion is NIL, you should poll the ioResult field of the

PPC parameter block (from your application's main event loop) to determine

whether the PPC Toolbox has completed the requested operation. A value in

the ioResult field other than 1 indicates that the call is complete. Note that it is

unsafe to poll the ioResult field at interrupt time since the PPC Toolbox may

be in the process of completing a call.

The sessRefNum field specifies a session identifier. Use the

session reference number returned from the completed PPCInform

parameter block to accept the session request.

Returns: an operating system Error Code.

noErr (0) No error

notInitErr (-900) PPC Toolbox has not been initialized yet

noGlobalsErr (-904) System unable to allocate memory, critical error

noSessionErr (-908) Invalid session reference number

badReqErr (-909) Invalid state for this operation
