HP-UX SNAplus2 CPI-C Programmer's Guide (June 2003)

Writing CPI-C Applications

Specifying the Local LU

Chapter 2 91

Context

If there is another TP from which the context is copied, the local LU

name is taken from that other TP. For more information about context,

see “Multiple Conversations” in Chapter 1.

APPCLLU Environment Variable

The local LU alias can be speciﬁed using the APPCLLU environment

variable.

For Unix On HP-UX systems this environment variable can be set in the following

ways:

• The program can issue a putenv() call

• You can set it in the HP-UX shell. For example, in the Korn shell you

would issue the following command:

export APPCLLU=MYLU

For Windows On Windows systems the local LU alias is speciﬁed in the registry. The

registry key is

\\HKEY_LOCAL_MACHINE\SOFTWARE\SNA

Client\SxClient\Parameters\MyExeName

where MyExeName is the ﬁle name of the program, less the .exe

extension.

The APPCLLU value under this registry key speciﬁes the LU alias.

End of Section Side Information

The local LU alias is part of the side information conﬁgured for each

symbolic destination name. TPs select which of these to use in the

Initialize_Conversation call.

NOTE Programs can modify the side information. For more information, see

“Administering Side Information”.
