+# reloadproc() #
|
|
|
+# Usage: reloadproc {--force} $BIN_FILE $MESSAGE #
|
|
|
+# #
|
|
|
+# Purpose: reloadproc sends a HUP signal to the running program (relaod #
|
|
|
+# configuration). It optionally, using the -force switch, checks the #
|
|
|
+# status of a particular program and starts it if it is not already #
|
|
|
+# running. #
|
|
|
+# #
|
|
|
+# Inputs: accepts one optional switch (must be the first argument), and #
|
|
|
+# either two, or zero string arguments. If BIN_FILE and MESSAGE are #
|
|
|
+# set in the calling envirnoment it will use those values, else it #
|
|
|
+# requires the bin file as the first argument (following -force if #
|
|
|
+# used), and the message as the second. If the --force argument is #
|
|
|
+# given, it follows the LSB definition of 'force-reload' - the #
|
|
|
+# program is started if not already running. #
|
|
|
+# #
|
|
|
+# Return values: 1 - generic error #
