Writing CPI-C Applications

Specifying the Local TP Name

Chapter 2 89

APPCTPN Environment Variable

The TP name can be speciﬁed using the APPCTPN environment

variable.

For Unix On HP-UX systems the TP name is speciﬁed in the APPCTPN

environment variable. 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 APPCTPN=MYTP

• If you are using automatically started invoked TPs, you can set it

using the environment ﬁeld of the SNAplus2 invokable TP data ﬁle

For Windows On Windows systems the TP name 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, without the .exe

extension.

The APPCTPN value under this registry key speciﬁes the TP name.

End of Section Default Value

If the TP name is not set by any of the methods described in the previous

sections then it is set to the default value CPIC_DEFAULT_TPNAME.
