Function Documentation

◆ accounting_add_bytes()

void accounting_add_bytes ( size_t  n_read,
size_t  n_written,
int  seconds 

Called from connection.c to tell us that seconds seconds have passed, n_read bytes have been read, and n_written bytes have been written.

◆ accounting_free_all()

void accounting_free_all ( void  )

Free all resources held by the accounting module

Definition at line 1254 of file hibernate.c.

◆ accounting_get_interval_length()

int accounting_get_interval_length ( void  )

If accounting is enabled, return how long (in seconds) this interval lasts.

◆ accounting_parse_options()

int accounting_parse_options ( const or_options_t options,
int  validate_only 

Configure accounting start/end time settings based on options->AccountingStart. Return 0 on success, -1 on failure. If validate_only is true, do not change the current settings.

◆ accounting_record_bandwidth_usage()

int accounting_record_bandwidth_usage ( time_t  now,
or_state_t state 

Save all our bandwidth tracking information to disk. Return 0 on success, -1 on failure.

◆ accounting_run_housekeeping()

void accounting_run_housekeeping ( time_t  now)

Invoked once per second. Checks whether it is time to hibernate, record bandwidth used, etc.

◆ configure_accounting()

void configure_accounting ( time_t  now)

Initialize the accounting subsystem.

◆ consider_hibernation()

void consider_hibernation ( time_t  now)

Consider our environment and decide if it's time to start/stop hibernating.

◆ get_accounting_bytes()

uint64_t get_accounting_bytes ( void  )

Return the relevant number of bytes sent/received this interval based on the set AccountingRule

◆ getinfo_helper_accounting()

int getinfo_helper_accounting ( control_connection_t conn,
const char *  question,
char **  answer,
const char **  errmsg 

Helper function: called when we get a GETINFO request for an accounting-related key on the control connection conn. If we can answer the request for question, then set *answer to a newly allocated string holding the result. Otherwise, set *answer to NULL.

Definition at line 1170 of file hibernate.c.

◆ hibernate_begin_shutdown()

void hibernate_begin_shutdown ( void  )

A wrapper around hibernate_begin, for when we get SIGINT.
