UaTk Internal Functions
The following table lists UaTk internal functions, which cannot be
called directly by your application. The information in this table may
be useful if you intend to write your own protocol library for another
programming language.
UaTk Internal Function and Description
_initialize
This function is used by the new( ) method for minimal initialization.
_logmsg
This function is an internal implementation of the LogMsg method. It is used for logging
by other internal functions and by LogMsg itself.
_logerr
This function is an internal implementation of the LogErr method. It is used for logging
errors by other internal functions and by LogErr itself.
_fmt_time
This function uses the localtime function to obtain data and time information, and formats
it in a standard fashion.
_check_input
This non-blocking function is used to detect data waiting on the input file handler. Blocking
may depend on the version of Perl being used. Using Perl 5.6 on UNIX and Windows NT
(using the cygwin port) does not block.
This function requires a time-out value as its only argument. It returns 0 (zero) if no data is
waiting, or greater than zero if data is waiting.
