- * OS Test - Silicon Graphics, Inc.
- * Mendota Heights, Minnesota
- *
- * TEST IDENTIFIER:  aiotcs02:  write/close flushes data to the file
- *
- * PARENT DOCUMENT:  aiotds01:  kernel i/o
- *
- * AUTHOR: Barrie Kletscher
- *
- * CO-PILOT: Dave Baumgartner
- *
- * TEST ITEMS:
- * 	for each open flags set used:
- * 	1. Multiple writes to a file work as specified for
- * 	   more than BUFSIZ bytes.
- * 	2. Multiple writes to a file work as specified for
- * 	   BUFSIZ bytes.
- * 	3. Multiple writes to a file work as specified for
- * 	   lower than BUFSIZ bytes.
- *
- * INPUT SPECIFICATIONS:
- * 	Standard parse_opts supported options.
- *$
- * OUTPUT SPECIFICATIONS
- * 	Standard tst_res output format
- *
- * ENVIRONMENTAL NEEDS:
- * 	This program uses the environment variable TMPDIR for the location
- * 	of the temporary directory.
- *
- *
- * SPECIAL PROCEDURAL REQUIREMENTS:
- * 	The program must be linked with tst_*.o and parse_opts.o.
- *
- * INTERCASE DEPENDENCIES:
- * 	NONE.
- *
- * DETAILED DESCRIPTION:
- * 	Attempt to get some memory to work with.
- * 	Call testrun writing (BUFSIZ + 1) bytes
- * 	Call testrun writing BUFSIZ bytes
- * 	Repeated call to testrun() with decreasing write sizes
- * 		less than BUFSIZ
- * 	End
- *
- * 	Start testrun()
- * 	Attempt to open a temporary file.
- * 	Write the memory to the file.
- * 	Attempt to close the file which also flushes the buffers.
- * 	Now check to see if the number of bytes written is the
- * 		same as the number of bytes in the file.
- * 	Cleanup
- *
- * BUGS:
- * 	NONE.
