tis_get_expiration(3)
NAME
  tis_get_expiration - Obtains a value representing a desired expiration time

SYNOPSIS
  #include <tis.h>

  int tis_get_expiration(
	  const struct timespec *delta,
	  struct timespec *abstime );

LIBRARY
  Standard C Library (libc.so, libc.a)

STANDARDS
  None

PARAMETERS
  delta
      Number of seconds and nanoseconds to add to the current system time.
      (The result is the time in the future.) This result will be placed in
      abstime.

  abstime
      Value representing the absolute expiration time. The absolute
      expiration time is obtained by adding delta to the current system time.
      The resulting abstime is in Universal Coordinated Time (UTC).

DESCRIPTION
  If threads are not present, this routine has no effect.

  This routine adds a specified time interval to the current absolute system
  time and returns a new absolute time. This new absolute time is used as the
  expiration time in a call to tis_cond_timedwait(3).

  The timespec structure contains the following two fields:

  tv_sec is an integral number of seconds.

  tv_nsec is an integral number of nanoseconds.

RETURN VALUES
  If an error condition occurs, this routine returns an integer value
  indicating the type of error. Possible return values are as follows:

  0   Successful completion.

  [EINVAL]
      The value specified by delta is invalid.

ERRORS
  None
