支持Xbase DBF格式的一套函数库的程序

Bullet Is...

 Bullet/95 is a thread-safe, multi-process capable database engine toolkit
 for Win32 (Win95 and NT) and Win32s (Win31).  It provides pre-built and
 tested access methods to data and index files for application programmers.
 It is not an end-user Database Management System (DBMS), but it is a tool
 that could be used to develop one.  Bullet is compact, efficient, and very
 fast.  It can be configured to use custom key-build, user sort-compare, and
 expression-parser routines to extend the built-in functionality.  All OS
 API calls made by Bullet can be replaced with custom calls, using most any
 compiler language.

 The standard data format is DBF (dBASE 3+ and later).  The supported memo
 format is DBT (dBASE 5 and later).  Index-only support can be enabled and
 with this any data file format may be used (the data maintained by the
 programmer then).  Also, the DBF standard may be extended by using binary
 field values and fields larger than 254 bytes.  Index files are
 NLS-compatible and use an efficient b-tree structure.  Files may be any
 size supported by the OS, up to 4GB.  Up to 1024 files may be opened and
 in use by any one process, with any number of processes active.

 The Bullet API consists of a wide assortment of routines, from low-level OS
 calls to high-level transaction-list routines that can process hundreds of
 files per transaction, with roll-back on error.  Network/multi-user
 support is included, and makes use of operating system features such as
 atomic re-locking (if available), and shared locks that allow other
 processes read-access to locked files.

 Also available are Bullet/X, for DOS 32-bit compilers and extenders;
 Bullet/2 for OS/2, and Bullet/2 REXX.  Bullet for 16-bit compilers is also
 available.
