  * This function uses fork/exec to create a new process. \a fds must be a
  * pointer to three integers, corresponding to stdin, stdout and stderr
  * respectively. It specifies how to deal with fd 0, 1, 2 in the child. The
  * contents of \a fds are interpreted as follows:
  *
- *     - fd[i] < 0: leave fd \a i alone
- *     - fd[i] = 0: dup fd \a i to /dev/null
+ *     - fd[i] < 0: leave fd \a i alone.
+ *     - fd[i] = 0: dup fd \a i to \p /dev/null.
  *     - fd[i] > 0: create a pipe and dup i to one end of that pipe.
  *     Upon return, fd[i] contains the file descriptor of the pipe.
  *
  *     In any case, all unneeded filedescriptors are closed.
  *
- * \return positive on success, negative on errors
