Detailed Description

Logging

Lws provides flexible and filterable logging facilities, which can be used inside lws and in user code.

Log categories may be individually filtered bitwise, and directed to built-in sinks for syslog-compatible logging, or a user-defined function.

Traditional logs use a single, processwide logging context. New style log apis (lws_xxx_cx()) can pass the logging context to use in.

struct lws_log_cx

Definition at line 80 of file lws-logs.h.

+ Collaboration diagram for lws_log_cx:
Data Fields
union lws_log_cx.u u
lws_log_use_cx_t refcount_cb

NULL, or a function called after each change to .refcount below, this enables implementing side-effects like opening and closing log files when the first and last object binds / unbinds

lws_log_prepend_cx_t prepend

NULL, or a cb to optionally prepend a string to logs we are a parent of

struct lws_log_cx * parent

NULL, or points to log ctx we are a child of

void * opaque

ignored by lws, used to pass config to emit_cx, eg, filepath

void * stg

ignored by lws, may be used a storage by refcount_cb / emit_cx

uint32_t lll_flags

mask of log levels we want to emit in this context

int32_t refcount

refcount of objects bound to this log context

LWS_VISIBLE LWS_EXTERN void lwsl_hexdump_level ( int level,
const void * vbuf,

#include <include/libwebsockets/lws-logs.h>

lwsl_hexdump_level() - helper to hexdump a buffer at a selected debug level

Parameters
levelone of LLL_ constants
vbufbuffer start to dump
lenlength of buffer to dump

If level is visible, does a nice hexdump -C style dump of vbuf for len bytes. This can be extremely convenient while debugging.

lwsl_hexdump() - helper to hexdump a buffer (DEBUG builds only)

Parameters
bufbuffer start to dump
lenlength of buffer to dump

Calls through to lwsl_hexdump_level(LLL_DEBUG, ... for compatability. It's better to use lwsl_hexdump_level(level, ... directly so you can control the visibility.

◆ lws_set_log_level()

LWS_VISIBLE LWS_EXTERN void lws_set_log_level ( int level,
lws_log_emit_t log_emit_function )

#include <include/libwebsockets/lws-logs.h>

lws_set_log_level() - Set the logging bitfield

Parameters
levelOR together the LLL_ debug contexts you want output from
log_emit_functionNULL to leave it as it is, or a user-supplied function to perform log string emission instead of the default stderr one.

log level defaults to "err", "warn" and "notice" contexts enabled and emission on stderr. If stderr is a tty (according to isatty()) then the output is coloured according to the log level using ANSI escapes.

You can set the default security level for logging using the secrecy_and_log_level() macro to set the level parameter, eg

lws_set_log_level(secrecy_and_log_level(LWS_SECRECY_PII, LLL_ERR | LLL_WARN), my_emit_function);

Normally you can just leave it at the default.

◆ lwsl_emit_syslog()

LWS_VISIBLE LWS_EXTERN void lwsl_emit_syslog ( int level,
const char * line )

#include <include/libwebsockets/lws-logs.h>

lwsl_emit_syslog() - helper log emit function writes to system log

Parameters
levelone of LLL_ log level indexes
linelog string

You use this by passing the function pointer to lws_set_log_level(), to set it as the log emit function, it is not called directly.

◆ lwsl_emit_stderr()

LWS_VISIBLE LWS_EXTERN void lwsl_emit_stderr ( int level,
const char * line )

#include <include/libwebsockets/lws-logs.h>

lwsl_emit_stderr() - helper log emit function writes to stderr

Parameters
levelone of LLL_ log level indexes
linelog string

You use this by passing the function pointer to lws_set_log_level(), to set it as the log emit function, it is not called directly.

It prepends a system timestamp like [2018/11/13 07:41:57:3989]

If stderr is a tty, then ansi colour codes are added.

LWS_VISIBLE LWS_EXTERN void lwsl_emit_stderr_notimestamp ( int level,

lwsl_emit_stderr_notimestamp() - helper log emit function writes to stderr

Parameters
levelone of LLL_ log level indexes
linelog string

You use this by passing the function pointer to lws_set_log_level(), to set it as the log emit function, it is not called directly.

If stderr is a tty, then ansi colour codes are added.

◆ lwsl_visible()

LWS_VISIBLE LWS_EXTERN int lwsl_visible ( int level)

#include <include/libwebsockets/lws-logs.h>

lwsl_visible() - returns true if the log level should be printed

Parameters
levelone of LLL_ log level indexes

This is useful if you have to do work to generate the log content, you can skip the work if the log level used to print it is not actually enabled at runtime.
