ESetGeneral

ESetGeneral Switch The .ENET Driver to general- transmission

mode.

#include <ENET.h> AppleTalk Manager

OSErr ESetGeneral( thePBptr, async);

EParamBlkPtr thePBptr; address of an EParamBlock structure

Boolean async; 0=await completion; 1=immediate return

returns Error Code; 0=no error

ESetGeneral switches The .ENET Driver from limited- transmission

mode to general-transmission mode.

thePBptr is a pointer to an EParamBlock structure. The relevant fields are as

follows:

Out-InName Type Size Offset Description

¨ ioResult short 2 16 Result code

Æ csCode short 2 26 Always ENetSetGeneral

async is a Boolean value. Use FALSE for normal ( synchronous) operation

or TRUE to function asynchronously. See Async I/O.

Returns: an operating system Error Code. It will be one of:

noErr (0) No error

memFullErr (-108) Insufficient memory in heap

limited-transmission mode to general-transmission mode. In

limited-transmission mode, The .ENET Driver allocates a write-data

buffer of 768 bytes. This buffer size is more than sufficient to hold an

EtherTalk data packet, which can be no larger than 621 bytes. In

general-transmission mode, The .ENET Driver can transmit an Ethernet

data packet of up to 1514 bytes.

The ioResult parameter returns the result of the function. If you call the

function asynchronously, the function sets this field to 1 as soon as it

begins execution, and it changes the field to the actual result code when it

completes execution. The csCode parameter is the routine selector,

automatically set by the high-level language interface. It is always

ENetSetGeneral for this function.

There is no command to switch The .ENET Driver from

general-transmission mode to limited-transmission mode. To switch back

to limited-transmission mode, you have to reset the driver by re starting

the computer.
