Why not use fork() and exec(), and simply don't call waitpid()?

Why not use fork() and exec(), and simply don't call waitpid()?

For example, you could do the following:

// ... your app code goes here ... pid = fork(); if( pid < 0 ) // error out here! if( !pid && execvp( /* process name, args, etc. */ ) // error in the child proc here! // ...parent execution continues here...
