Launch web page from my application

Question

Ok, this probably has a really simple answer, but I\'ve never tried to do it before: How do you launch a web page from within an app? You know, \"click here to go to our FAQ\",

Answer 1

For the record (since you asked for a cross-platform option), the following works well in Linux:

#include 
#include 

void launch(const std::string &url)
{
  std::string browser = getenv("BROWSER");
  if(browser == "") return;

  char *args[3];
  args[0] = (char*)browser.c_str();
  args[1] = (char*)url.c_str();
  args[2] = 0;

  pid_t pid = fork();
  if(!pid)
    execvp(browser.c_str(), args);
}

Use as:

launch("http://example.com");
