WindSh Environment Variables
WindSh allows you to change the behavior of a particular shell session by setting
several environment variables. The Tcl procedure shConfig allows you to display
and set how I/O redirection, C++ constructors and destructors, loading, and the
load path are defined and handled by the shell.

WindSh Environment Variables
Variable
SH_GET_TASK_IO
LD_CALL_XTORS
LD_SEND_MODULES
LD_PATH
Result
Sets the I/O redirection mode for called functions.
The default is “on”, which redirects input and output
of called functions to WindSh. To have input and
output of called functions appear in the target
console, set SH_GET_TASK_IO to “off.”
Sets the C++ strategy related to constructors and
destructors. The default is “target”, which causes
WindSh to use the value set on the target using
cplusXtorSet( ). If LD_CALL_XTORS is set to “on”,
the C++ strategy is set to automatic (for the current
WindSh only). “Off” sets the C++ strategy to manual
for the current shell.
Sets the load mode. The default “on” causes modules
to be transferred to the target server. This means that
any module WindSh can see can be loaded. If
LD_SEND_MODULES if “off”, the target server
must be able to see the module to load it.
Sets the search path for modules using the separator
“;”. When a ld() command is issued, WindSh first
searches the current directory and loads the module
if it finds it. If not, WindSh searches the directory
path for the module.
