# procd API:
|

#
|
||||
# procd_open_service(name, [script]):
|
||||
# Initialize a new procd command message containing a service with one or more instances
|
||||
#
|
||||
# procd_close_service()
|
||||
# Send the command message for the service
|
||||
#
|
||||
# procd_open_instance([name]):
|
||||
# Add an instance to the service described by the previous procd_open_service call
|
||||
#
|
||||
# procd_set_param(type, [value...])
|
||||
# Available types:
|
||||
# command: command line (array).
|
||||
# respawn info: array with 3 values $fail_threshold $restart_timeout $max_fail
|
||||
# env: environment variable (passed to the process)
|
||||
# data: arbitrary name/value pairs for detecting config changes (table)
|
||||
# file: configuration files (array)
|
||||
# netdev: bound network device (detects ifindex changes)
|
||||
# limits: resource limits (passed to the process)
|
||||
# user: $username to run service as
|
||||
# group: $groupname to run service as
|
||||
# pidfile: file name to write pid into
|
||||
# stdout: boolean whether to redirect commands stdout to syslog (default: 0)
|
||||
# stderr: boolean whether to redirect commands stderr to syslog (default: 0)
|
||||
# facility: syslog facility used when logging to syslog (default: daemon)
|
||||
#
|
||||
# No space separation is done for arrays/tables - use one function argument per command line argument
|
||||
#
|
||||
# procd_close_instance():
|
||||
# Complete the instance being prepared
|
||||
#
|
||||
# procd_running(service, [instance]):
|
||||
# Checks if service/instance is currently running
|
||||
#
|
||||
# procd_kill(service, [instance]):
|

# Kill a service instance (or all instances)
|
