- manx is distributed in a single compressed file manxRL.zip; R and L
- would be the release and level numbers, respectively. The ZIP data
- compression utilities are needed to extract the individual files.
-
- The following files are obtained by decompressing manxRL.zip:
-
- manx.rme preliminary information
- license.txt license
- ansi.h ANSI compatibility header
- makefile UNIX makefile
- manx.c manx source code
- manx.frm sample manual entry form

- MANX
-
- The manx utility extracts manual entries from source files. The files
- are read from stdin and the manual entries are written to stdout.
- Each individual manual entry is broken into pages separated by form
- feeds and terminated with a form feed. The manx manual entry located
- in manx.c contains a more detailed description.
-
- The manx utility was originally developed for cbase, a complete
- multiuser C database file management library developed by Citadel. A
- trial copy of cbase may be obtained on the Citadel BBS.
-
- ======================================================================
- INSTALLATION INSTRUCTIONS
-
- Since C compilers are currently at various stages of ANSI compliance,
- the user must specify to manx what ANSI features are supported by
- his compiler. This is done by setting a set of ANSI compatibility
- macros that have been isolated in the file ansi.h. For instance, the
- macro AC_PROTO should be defined if function prototypes are supported.
- As distributed, ansi.h is set up for a fully ANSI compliant compiler.
- After ansi.h is set up, it should be copied to the include directory.
- Isolating these definitions in a separate header outside of manx
- allows ansi.h to be readily available to other applications.
-
- Exact installation procedures for DOS vary. The instructions below
- are for Borland Turbo C.
-
-

- UNIX
- 1. Compile manx.
- $ make manx
- 2. Install manx. This will copy manx to /usr/bin.
- $ su
- # make install
- # ^d
- 3. Extract and print manx manual entry.
- $ make man
- $ lp manx.man
-
-
- DOS
- 1. Compile manx.
- > tcc -O -A -ms manx.c
- 2. Install manx by copying it to a directory in the path.
- > copy manx.exe c:\usr\bin
- > del manx.exe
- 3. Extract and print manx manual entry.
- > type manx.c | manx > manx.man
- > print manx.man

- | cbase - The C Database Library |
- | Version 1.0.2 |
- ----------------------------------------------------------------------
-
- cbase is a complete multiuser C database file management library,
- providing indexed and sequential access on multiple keys. It features
- a layered architecture and comprises four individual libraries.

- -----------------------------------
- cbase Libraries
-
- The four libraries are:
-
- cbase - C database library for indexed and sequential access
- lseq - doubly linked sequential file management library
- btree - B+-tree file management library
- blkio - block buffered input/output library
-
- cbase internally uses lseq for record storage and btree for inverted
- file index storage, which in turn use blkio for file access and
- buffering. blkio is analagous to stdio but based on a file model more
- appropriate for structured files such as used in database software.
-
- The lower level libraries can also be accessed directly for use
- independent of cbase. For example, the btree library can be used to
- manipulate B+-trees for purposes other than inverted files, and the
- blkio library to develop new structured file management libraries.
-
-
- * ISAM stands for Indexed Sequential Access Method.

- cbase Features
- --------------
- Portable:
- - Written in strict adherence to ANSI C standard.
- - K&R C compatibility maintained.
- - All operating system dependent code is isolated to a small portion
- of the blkio library to make porting to new systems easy.
- - UNIX and DOS currently supported.
- Buffered:
- - Both records and indexes are buffered using LRU (least recently
- used) buffering.
- Fast and efficient random access:
- - B+-trees are used for inverted file key storage.
- - Multiple keys are supported.
- - Both unique and duplicate keys are supported.
- Fast and efficient sequential access:
- - B+-trees also allow keyed sequential access.
- - Records are stored in doubly linked lists for non-keyed sequential
- access.
- - Both types of sequential access are bidirectional.
- Multiuser:
- - Read-only locking.
- Other Features:
- - Text file data import and export.
- - Custom data types can be defined.
- - Marker used to detect corrupt files.
- - Reference documentation is in standard UNIX manual entry format,
- including errno values.
- Utilities:
- - cbddlp, a data definition language processor, is provided to
- automatically generate the C code defining a database.
-
