It requires very minimalsupport from external libraries or from the operating system.This makes it well suited for use in embedded devices thatlack the support infrastructure of a desktop computer. Thisalso makes SQLite appropriate for use within applications thatneed to run without modification on a wide variety of computersof varying configurations.</p><p>SQLite is written in ANSI-C and should be easily compiled byany standard C compiler. It makes minimal use of the standard Clibrary. The only required C library functions called are:</p><ul><li> memset()<li> memcpy()<li> memcmp()<li> strcmp()<li> malloc(), free(), and realloc()</ul><p>SQLite can be configured at compile-time to use a staticbuffer in place of calling malloc for the memory it needs.The date and time SQL functions provided by SQLite requiresome additional C library support, but those functions canbe also be omitted from the build using compile-time options.</p><p>Communications between SQLite and the operating system and disk aremediated through an interchangable Virtual File System (VFS) layer.VFS modules for Unix (linux and MacOSX), OS/2, Win32, and WinCE areprovided in the source tree. It is a simple matter to devise analternative VFS for embedded devices. </p><p>The SQLite source code is available as an"amalgamation" - a single large C source code file.Projects that want to include SQLite can do so simplyby dropping this one source file (named "sqlite3.c") andits corresponding header ("sqlite3.h") into their sourcetree and compiling it together with the rest of thecode. SQLite does not link against any external libraries(other than the C library, as described above) and doesnot require any special build support.</p><hr><small><i>This page last modified 2008/03/03 13:41:48 UTC</i></small></div></body></html>?? 快捷鍵說明
