after the entry pt of an exe it is the main function that is called first ( actually loaded into stack trace )
i am not sure of this,
if you want some other function to execute first
then you need to have your exe generator, with options to work at the entry pt level of any exe

Hi,
I have a main loop which calls a sub loop, which finally returns to the main loop itself. The main loop runs when a flag is set. Now, I have a signal handler for SIGINT, which resets the flag and thus stops the main loop. Suppose I send SIGINT while the program is in subloop, I get an error... (1 Reply)

H friends,
As we know, a function returns a value and that value is saved somwhere. like
int Sum( int x, int y )
{
return x + y;
}
Total = Sum( 10, 20 );
The value 30 is saved in variable Total.
Now the question is, what int value does the function main return, and where is it... (5 Replies)

BCOMPILER_WRITE_EXE_FOOTER(3) 1 BCOMPILER_WRITE_EXE_FOOTER(3)
bcompiler_write_exe_footer - Writes the start pos, and sig to the end of a exe type file
SYNOPSIS
bool bcompiler_write_exe_footer (resource $filehandle, int $startpos)
DESCRIPTION
An EXE (or self executable) file consists of 3 parts:
o 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)
oThe Bytecodes (uncompressed only for the moment)
oThe 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.
PARAMETERS
o $filehandle
- A file handle as returned by fopen(3).
o $startpos
- The file position at which the Bytecodes start, and can be obtained using ftell(3).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
bcompiler_write_exe_footer(3) example
<?php
/* creating the output file (example.exe) */
$fh = fopen("example.exe", "w");
/* 1) writing a stub (phpe.exe) */
$size = filesize("phpe.exe");
$fr = fopen("phpe.exe", "r");
fwrite($fh, fread($fr, $size), $size);
$startpos = ftell($fh);
/* 2) writing bytecodes */
bcompiler_write_header($fh);
bcompiler_write_class($fh, "myclass");
bcompiler_write_function($fh, "main");
bcompiler_write_footer($fh);
/* 3) writing EXE footer */
bcompiler_write_exe_footer($fh, $startpos);
/* closing the output file */
fclose($fh);
?>

Warning
This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in
