put_select_single_np(2) OSS System Calls Reference Manual
• Compile the application using the -Wlp64 compiler command option.
• Link the application to the yputdll library (/G/system/zdllnnn/yputdll).
NOTES
To use a combination of the default thread-aware select() and the put_select_single_np() func-
tions in a single source file, you must compile the application using the _PUT_MODEL_ feature
test macro only and explicitly call put_select_single_np().

• If the file descriptor becomes invalid (is closed by another thread), -1 is returned with an
errno of [EBADF].
• If a signal is received via the pthread_kill() function and is not blocked, ignored, or
