| #define N_LOGGING_DOMAINS 20 |
Number of logging domains in the code.
| typedef void(* log_callback)(int severity, uint32_t domain, const char *msg) |
Callback type used for add_callback_log.
| int add_callback_log | ( | const log_severity_list_t * | severity, | |
| log_callback | cb | |||
| ) |
Add a log handler to send messages in severity to the function cb.

| int add_file_log | ( | const log_severity_list_t * | severity, | |
| const char * | filename | |||

Add a log handler to send messages to filename. If opening the logfile fails, -1 is returned and errno is set appropriately (by open(2)).

| void add_stream_log | ( | const log_severity_list_t * | severity, | |
| const char * | name, | |||
| int | fd | |||

Add a log handler named name to send all messages in severity to fd. Steals a reference to severity; the caller must not use it after calling this function.

| int add_syslog_log | ( | const log_severity_list_t * | severity | ) |
Add a log handler to send messages to they system log facility.

| const char* log_level_to_string | ( | int | level | ) |
Return the string equivalent of a given log level.

| void log_set_application_name | ( | const char * | name | ) |
Set the "application name" for the logs to name: we'll use this name in the message we write when starting up, and at the start of each new log.
Tor uses this string to write the version number to the log file.

| int parse_log_level | ( | const char * | level | ) |
If level is a valid log severity, return the corresponding numeric value. Otherwise, return -1.
Referenced by parse_log_severity_config().
| int parse_log_severity_config | ( | const char ** | cfg_ptr, | |
| log_severity_list_t * | severity_out | |||
| ) |
Parse a log severity pattern in *cfg_ptr. Advance cfg_ptr after the end of the severityPattern. Set the value of severity_out to the parsed pattern. Return 0 on success, -1 on failure.
The syntax for a SeverityPattern is:
SeverityPattern = *(DomainSeverity SP)* DomainSeverity
DomainSeverity = (DomainList SP)? SeverityRange
SeverityRange = MinSeverity ("-" MaxSeverity )?
DomainList = "[" (SP? DomainSpec SP? ",") SP? DomainSpec "]"
DomainSpec = "*" | Domain | "~" Domain
A missing MaxSeverity defaults to ERR. Severities and domains are case-insensitive. "~" indicates negation for a domain; negation happens last inside a DomainList. Only one SeverityRange without a DomainList is allowed per line.
