23 | /* Make the process sleep for SECONDS seconds, or until a signal arrives | |
24 | and is not ignored. The function returns the number of seconds less | |
25 | than SECONDS which it actually slept (zero if it slept the full time). | |
26 | If a signal handler does a `longjmp' or modifies the handling of the | |
27 | SIGALRM signal while inside `sleep' call, the handling of the SIGALRM | |
28 | signal afterwards is undefined. There is no return value to indicate | |
29 | error, but if `sleep' returns SECONDS, it probably didn't work. */ | |
