Top Forums Programming Problem with pthread_delay_np Post 302434985 by proximity4 on Tuesday 6th of July 2010 05:47:25 AM

The pthread_delay_np function exists on Tru64 UNIX, but not on HP-UX. This function will be available on a temporary basis in the Tru64 UNIX Migration Environment for HP-UX.

The pthread_delay_np function is a nonportable equivalent to the POSIX standard function nanosleep. Both accept a time interval using a standard POSIX struct timespec structure, which defines the interval in seconds and nanoseconds, and suspend the calling thread for at least as long as the specified interval. The major functional difference is that pthread_delay_np is based on a timed condition variable wait: it computes an absolute target time by adding the interval to the current system time, and waits until that target time arrives, disregarding any signals delivered to the thread. Changes to the system time will affect the actual interval waited. The nanosleep function waits for the specified interval regardless of system time changes; however, if a signal is delivered to the thread, and dismissed normally, nanosleep will return to the caller and can optionally return the remaining interval.

The Migration Environment contains Tru64 UNIX APIs, development tools, and commands and utilities to assist customers in migrating their applications from Tru64 UNIX to HP-UX.

NANOSLEEP(2)						      BSD System Calls Manual						      NANOSLEEP(2)

NAME
nanosleep -- suspend process execution for an interval measured in nanoseconds LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <time.h> int nanosleep(const struct timespec *rqtp, struct timespec *rmtp); DESCRIPTION
The nanosleep() system call causes the calling thread to sleep until the time interval specified by rqtp has elapsed. An unmasked signal will cause it to terminate the sleep early, regardless of the SA_RESTART value on the interrupting signal. RETURN VALUES
If the nanosleep() system call returns because the requested time has elapsed, the value returned will be zero. If the nanosleep() system call returns due to the delivery of a signal, the value returned will be -1, and the global variable errno will be set to indicate the interruption. If rmtp is non-NULL, the timespec structure it references is updated to contain the unslept amount (the request time minus the time actually slept). ERRORS
The nanosleep() system call fails if: [EFAULT] Either rqtp or rmtp points to memory that is not a valid part of the process address space. [EINTR] The nanosleep() system call was interrupted by the delivery of a signal. [EINVAL] The rqtp argument specified a nanosecond value less than zero or greater than or equal to 1000 million. [ENOSYS] The nanosleep() system call is not supported by this implementation. SEE ALSO
sigsuspend(2), sleep(3) STANDARDS
The nanosleep() system call conforms to IEEE Std 1003.1b-1993 (``POSIX.1''). BSD
