(PECL)

bcompiler_write_exe_footer -- Writes the start pos, and sig to the end of a exe type file

Beskrivelse

bool bcompiler_write_exe_footer ( resource filehandle, int startpos )

An EXE (or self executable) file consists of 3 parts:

The stub (executable code, e.g. a compiled C program) that loads PHP interpreter, bcompiler extension, stored Bytecodes and initiates a call for the specified function (e.g. main) or class method (e.g. main::main)
The Bytecodes (uncompressed only for the moment)
The bcompiler EXE footer

To obtain a suitable stub you can compile php_embed-based stub phpe.c located in the examples/embed directory on bcompiler's CVS.

Parameterliste

filehandle

A file handle as returned by fopen().

startpos

The file position at which the Bytecodes start, and can be obtained using ftell().

Returneringsværdier
