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

				############################################################ 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->path = (string)copyinstr(arg0);
				printf("lchmod(path \"%s\", mode %04o)", this->path, (mode_t)arg1);

				asomersUnsubmitted Done Inline Actions Instead of hardcoding "lchmod" here (and in chmod, fchmod, and kill), could this be determined from a builtin dtrace variable? That would reduce the diffs between the different scripts. asomers: Instead of hardcoding "lchmod" here (and in chmod, fchmod, and kill), could this be determined…
				dteskeAuthorUnsubmitted Done Inline Actions chmod, fchmod, and kill take different arguments. Changing the function name to "%s" and using a variable doesn't address the fact that the arguments that follow are different and as-such the format string to the printf will still differ. dteske: chmod, fchmod, and kill take different arguments.
