|
||||
|
||||
#### log_set_quiet(bool enable)
|
||||
Quiet-mode can be enabled by passing `true` to the `log_set_quiet()` function.
|
||||
While this mode is enabled the library will not output anything to `stderr`, but
|
||||
will continue to write to files and callbacks if any are set.
|
||||
|
||||
|
||||
#### log_set_level(int level)
|
||||
The current logging level can be set by using the `log_set_level()` function.
|
||||
All logs below the given level will not be written to `stderr`. By default the
|
||||
level is `LOG_TRACE`, such that nothing is ignored.
|
||||
|
||||
|
||||
#### log_add_fp(FILE *fp, int level)
|
||||
One or more file pointers where the log will be written can be provided to the
|
||||
library by using the `log_add_fp()` function. The data written to the file

|
||||
Any messages below the given `level` are ignored. If the library failed to add a
|
||||
file pointer a value less-than-zero is returned.
|
||||
|
||||
|
||||
#### log_add_callback(log_LogFn fn, void *udata, int level)
|
||||
One or more callback functions which are called with the log data can be
|
||||
provided to the library by using the `log_add_callback()` function. A callback
|
||||
function is passed a `log_Event` structure containing the `line` number,
|
||||
`filename`, `fmt` string, `va` printf va\_list, `level` and the given `udata`.
|
||||
|
||||
|
||||
#### log_set_lock(log_LockFn fn, void *udata)
|
||||
If the log will be written to from multiple threads a lock function can be set.
|
||||
The function is passed the boolean `true` if the lock should be acquired or
|
||||
`false` if the lock should be released and the given `udata` value.
|
||||
|
||||
|
||||
#### const char* log_level_string(int level)
|
||||
Returns the name of the given log level as a string.
|
||||
|
||||
|
||||
#### LOG_USE_COLOR
|
||||
If the library is compiled with `-DLOG_USE_COLOR` ANSI color escape codes will
|
||||
be used when printing.
|
||||
|
||||
#### LOG_DONT_CODE
|
||||
If the library is compiled with `-DLOG_DONT_CODE`, then the source code file name
|
||||
and line number will be removed from the output.
