Thanks! Well this works:
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
int main() {
int child;
printf("Running\n");
if ((child=fork()) != 0) { printf("Forked %d\n",child); exit(0); }
setsid();
if ((child=fork()) != 0) { exit(0); }
close(0); close(1); close(2);
while(1){
FILE *f= fopen("log.log","w");
fprintf(f,"Daemon running\n");
fclose(f);
sleep(5);
}
}
I guess I use open() then dup2() to create fd's for 0,1,2 so
the webserver can still do I/O.. not sure what happens
to C++ streams cin, cout, cerr or C streams stdin, stdout. stderr
though (I presume they will just keep working since underneath
they have to use the unix fds ..?)
