/* Define how to access the int that the wait system call stores.

This has been compatible in all Unix systems since time immemorial,
|
|
||||||
but various well-meaning people have defined various different
|
|
||||||
words for the same old bits in the same old int (sometimes claimed
|
|
||||||
to be a struct). We just know it's an int and we use these macros

to access the bits. */

in POSIX.1. We fail to define WNOHANG and WUNTRACED, which POSIX.1

<sys/wait.h> defines, since our code does not use waitpid(). We
|
|
||||||
also fail to declare wait() and waitpid(). */
