Module Name:

|
|
|
routing\ip\rtrmgr\compare.c
|
|
|
|
Abstract:
|
|
File contains the following functions
|
|
PortCmp
|
|
Cmp
|
|
InetCmp
|
|
UdpCmp
|
|
TcpCmp
|
|
IpNetCmp
|
|
|
|
All these functions behave like strcmp. They return >0 if first argument is greater
|
|
than the second, <0 if the second is greater than the first and 0 if they are equal
|
|
|
|
These functions should be revised to make them more effecient
|
|
|
|
Revision History:
|
|
|
|
Amritansh Raghav 6/8/95 Created
|
|
Amritansh Raghav 10/18/95 The functions now return >0,0,<0 instead of +1,0,-1
