I don't know anything about those netscape functions, but they sound
like generic file I/O.

Have a look at apr_file_open() and friends in apr_file_io.h.  The
APR_APPEND flag causes I/O to do the right thing for log files
(serialize among multiple threads and/or processes), but note that
there is a critical fix for that support on Win32 after Apache
2.0.43.
