Module Name:
|
||
|
|
|
||
|
|
rxmsg.c
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
Routines in this module implement the functionality required to remote the
|
||
|
|
NetMessage APIs to down-level servers
|
||
|
|
|
||
|
|
Contains RxNetMessage routines:
|
||
|
|
RxNetMessageBufferSend
|
||
|
|
RxNetMessageNameAdd
|
||
|
|
RxNetMessageNameDel
|
||
|
|
RxNetMessageNameEnum
|
||
|
|
RxNetMessageNameGetInfo

|
Environment:
|
||
|
|
|
||
|
|
Win-32/flat address space
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
Routines in this module assume that caller-supplied parameters have
|
||
|
|
already been verified. No effort is made to further check the veracity
|
||
|
|
of parms. Any actions causing exceptions must be trapped at a higher
|
||
|
|
level. This applies to ALL parameters - strings, pointers, buffers, etc.
