a program that opens the browser

[Ali.B]

hello people,
i want to write a program in c, that when i run it, it should open the browser ( firefox , since I'm using Linux) and goes to a given URL automatically, like:
http://localhost:8080/something.html
this URL should be hard coded.
how can I do this? a sample code or example would be really nice
thanking you in advance

Look into the spawnvpe function (passing P_NOWAIT as the first parameter).

[Ali.B]

can u show me with an example code?

[Sebastiani]

Can you read documentation?

Dint really wanted to post the code. But i've been good to you today :-/

#include <process.h>

int main()
{
    int pid;
    
    if( ( pid = spawnvp( P_NOWAIT, "mozilla", "www.google.co.uk" ) ) != 0 )
        printf("New process created!\n");
    else
        printf("Error: spawnvp failed.\n");
    
    return 0;
}

thanks, but do i need to compile it agains any library? cuz this is my output when i compile it with this command:

 #:~/Desktop/ex/bt/http$ gcc url.c -o url

the output:

url.c:1:21: error: process.h: No such file or directory
url.c: In function ‘main’:
url.c:6: error: ‘P_NOWAIT’ undeclared (first use in this function)
url.c:6: error: (Each undeclared identifier is reported only once
url.c:6: error: for each function it appears in.)
url.c:7: warning: incompatible implicit declaration of built-in function ‘printf’

spawnvp is depreciated on *nix. Read the GNU manual on execvp() instead.

execvp() example code

Try #include <unistd.h> and execvp() or fork().

Hmm. I had always assumed they were standard functions. I guess not, though.
