SHTK_CLEANUP_REGISTER(3) BSD Library Functions Manual SHTK_CLEANUP_REGISTER(3)

NAME
     shtk_cleanup_register -- Installs cleanup handlers	to be called on	script
     termination

LIBRARY
     shtk_import cleanup

SYNOPSIS
     shtk_cleanup_register handler1 [..	handlerN]

DESCRIPTION
     The shtk_cleanup_register function	installs one or	more cleanup handlers,
     given in the handler1 to handlerN arguments as function names.

     The registered handlers are executed in the order they are	originally
     registered.  Registration of handlers is idempotent.

EXAMPLES
     The following example creates a temporary file and	installs a cleanup
     handler to	ensure that the	file gets removed when the script terminates:

	   local pattern="${TMPDIR:-/tmp}/my_program.XXXXXX"

	   local temp_file="$(mktemp "${pattern}" 2>/dev/null)"
	   [ -f	"${temp_file}" ] || shtk_cli_error "Failed to create temporary file"

	   eval	"remove_temp_file() { rm -f '${temp_file}'; }"
	   shtk_cleanup_register remove_temp_file
