/* FIXME: From sys/sysvi386/sys */ #ifndef _WAIT_H # define _WAIT_H # define WNOHANG 1 # define WUNTRACED 2 /* * Unlike the atrocity that BSD ended up using, we do not have a "union * wait," although I could probably implement one. Given the code I * sometimes end up porting, it might be a good thing. Anyway, the * format of a stat thingy, filled in by the wait*() routines, is: * struct { * int filler:16; * union { * struct stopped { * int signo:8; * int o177:8; // will be 0177 * }; * struct exited { * int retval:8; * int zero:8; // 0, obviously 8-) * }; * struct termed { * int zero:8; // zeroes * int corep:1; // was there a core file? * int signo:7; // what?! Only 127 signals?! * }; * int value:16; * }; * }; * * Braver souls than I can turn that into a union wait, if desired.
