running binary using C

fs11 · 09-07-2007, 08:00 PM

Hello all,

I am trying to run a binary (which is obtained from compiling another C/C++ code)using a C code...

For example:

MY new C Program {

RUN(thebinary) //the binary obtained from compiling another C/C++ code

}

Any help would be highly appreciable...

Thanks

Hey,

The execve system call executes another program within a program. See man 2 execve.

Is that any use...

dear fs11

If u wanna run a binary then u can also use execl() call.

for example ur binary name is sample.bin and it is located in /root/sample.bin then write ur program as following,

int main(int argc, char **argv)
{
int t=0;
t=execl("/root/sample.bin","/root/sample.bin",(char*)0);

if(t==-1){
perror("EXECL FAILED");
}
return 0;
}

If u want to run ur binary sepratly from ur program use fork() sys call.

cheers !!!!!
