21 /* Like system(3), but with error messages printed if the fork fails
22 or if the child process dies due to an uncaught signal. Also, the
23 return value is a bit simpler:
25 -1 if there was any problem
26 Otherwise, the 8-bit return value of the program ala WEXITSTATUS
27 as defined in <sys/wait.h>.
