				# $Title: dwatch(8) module for nanosleep(2) entry $
				# $Copyright: 2014-2017 Devin Teske. All rights reserved. $
				# $FreeBSD$
				#
				############################################################ DESCRIPTION
				#
				# Print arguments being passed to nanosleep(2)
				#
				############################################################ PROBE

				# This is optional, if you don't set or it is NULL, dwatch(8) will try to
				# dynamically determine the probe via the module's filename. For example, if
				# the module file is named `foo' then dwatch(8) will try `dtrace -ln foo:entry'
				# to determine an appropriate probe for watching `foo'.

				PROBE=syscall::nanosleep

				############################################################ ACTIONS

				# Optional actions to be performed before hitting the final print action

				#exec 9<<EOF
				#EOF
				#ACTIONS=$( cat <&9 )
				#ID=

				############################################################ PRINT ACTION

				# The default value is simply `entry'. This is paired with $PROBE (which can be
				# auto-probed when unset or NULL) and can be customized to include clauses for
				# the final print action which must be true before the print action will run.

				#PRINT=

				############################################################ EVENT TAG

				# The EVENT_TAG is run inside the print action after the timestamp has been
				# printed. By default, `UID.GID CMD[PID]: ' of the process is printed.

				#exec 9<<EOF
				#EOF
				#EVENT_TAG=$( cat <&9 )

				############################################################ DETAILS

				# The DETAILS are run after the EVENT_TAG and by default, the program name and
				# arguments of the process hitting the PRINT action are shown. This can be
				# customized to call-specific information because the `-v' flag of dwatch(8)
				# can provide detailed process information for the PRINT action on lines below
				# the DETAILS.
				#
				# NB: Should produce a single-line and not print a trailing newline.

				exec 9<<EOF
				this->rqtp = (struct timespec *)copyin(arg0, sizeof(struct timespec));
				this->rmtp = (struct timespec *)copyin(arg1, sizeof(struct timespec));
				printf("nanosleep(rqtp {%d, %d}, rmtp {%d, %d})",
				this->rqtp->tv_sec, this->rqtp->tv_nsec,
				this->rmtp->tv_sec, this->rmtp->tv_nsec);
				EOF
				DETAILS=$( cat <&9 )
