DESCRIPTION:
Sets the location of the debug log file.

HEADER:
pmapi.h

PARAMETERS:
logFilePath - Full file and path name to debug log file.

REMARKS:
Sets the name and location of the debug log file. The debug log file is
created and written to when runtime checks, warnings and failure conditions
are logged to disk when code is compiled in CHECKED mode. By default the
log file is called 'scitech.log' and goes into the current SciTech Nucleus
path for the application. You can use this function to set the filename
and location of the debug log file to your own application specific
directory.
