- NAME
-
- fstat - display complete list of currently open files
-
-
-
- SYNOPSIS
-
- fstat
-
-
-
- DESCRIPTION
-
- fstat.com is a program to display all of the currently open files
-
- and devices known to the system. It also shows length, current
-
- offset, number of handles referring to this file, drive or device
-
- type, and program which opened the file. The standard devices
-
- CON, AUX, PRN, etc. are also listed since they use file handles.
-
- The program might be useful for diagnosing "too many files open"
-
- type messages, since it will show what files are in use by TSRs
-
- in addition to those opened by a foreground program. It works by
-
- using DOS service 52H, the "list of lists" interrupt, which
-
- returns pointers to most of the internal DOS kernel tables,
-
- including the file tables. It should work for all DOS versions
-
- 2+, although only 3+ can find out the name of the program which
-
- opened any given file. There is some version specific code for
-
- 4.x and it is possible that this may not work on all systems
-
- since the contents of the system tables are not fully documented.

-
- BUGS
-
- This seems to work, but it would be nice if this information were made
-
- "official" instead of needing to rely on the usenet "interrupt list"
-
- for the necessary information
-
- It is usually not possible to retrieve the name of a shell (such as
-
- command.com) so it is listed as "-shell-".
