Integer_Type XPA_MAXHOSTS

Description

This variable contains the maximum number of hosts (i.e. XPA servers) that will be contacted by a XPA call. It can be over-ridden for the XPASet(), XPAGet(), and XPAGEtToFile() functions by supplying a value for the max_rec parameter.

When the xpa module is imported, the XPA_MAXHOSTS variable is set to the value of the XPA_MAXHOSTS environment variable, of 5 if the environment variable does not exist.
