Function Documentation

◆ parse_process_specifier()

static int parse_process_specifier ( const char *  process_spec,
struct parsed_process_specifier_t ppspec,
const char **  msg 
)
static

Parse the process specifier given in process_spec into *ppspec. Return 0 on success; return -1 and store an error message into *msg on failure. The caller must not free the returned error message.

Definition at line 70 of file procmon.c.

◆ tor_process_monitor_free_()

void tor_process_monitor_free_ ( tor_process_monitor_t procmon)

Free the process-termination monitor procmon.

Definition at line 325 of file procmon.c.

References tor_process_monitor_t::e.

◆ tor_process_monitor_new()

tor_process_monitor_t* tor_process_monitor_new ( struct event_base *  base,
const char *  process_spec,
log_domain_mask_t  log_domain,
tor_procmon_callback_t  cb,
void *  cb_arg,
const char **  msg 
)

Create a process-termination monitor for the process specifier given in process_spec. Return a newly allocated tor_process_monitor_t on success; return NULL and store an error message into *msg on failure. The caller must not free the returned error message.

When the monitored process terminates, call cb(cb_arg).

Definition at line 181 of file procmon.c.

◆ tor_process_monitor_poll_cb()

static void tor_process_monitor_poll_cb ( periodic_timer_t event,
void *  procmon_ 
)
static

Libevent callback to poll for the existence of the process monitored by procmon_.

Definition at line 248 of file procmon.c.

References tor_assert().

◆ tor_validate_process_specifier()

int tor_validate_process_specifier ( const char *  process_spec,
const char **  msg 
)

Verify that the process specifier given in process_spec is syntactically valid. Return 0 on success; return -1 and store an error message into *msg on failure. The caller must not free the returned error message.
