Detailed Description

logging and debugging output.

Todo:: Have a bit set in the log level that says not to include the function name.

Definition in file trace.c.

Function Documentation

◆ rs_trace_to()

void rs_trace_to ( rs_trace_fn_t * new_impl )

Set the destination of trace information.

Set trace callback.

The callback scheme allows for use within applications that may have their own particular ways of reporting errors: log files for a web server, perhaps, and an error dialog for a browser.

Todo:: Do we really need such fine-grained control, or just yes/no tracing?

Definition at line 65 of file trace.c.

◆ rs_trace_set_level()

void rs_trace_set_level ( rs_loglevel level )

Set the least important message severity that will be output.

Definition at line 70 of file trace.c.

◆ rs_supports_trace()

int rs_supports_trace ( void )

Check whether the library was compiled with debugging trace.

Returns: True if the library contains trace code; otherwise false.

If this returns false, then trying to turn trace on will achieve nothing.

Variable Documentation

◆ rs_severities

const char* rs_severities[]

static

Initial value:

= {
    "EMERGENCY! ", "ALERT! ", "CRITICAL! ", "ERROR: ", "Warning: ",
    "", "", ""
}

Log severity strings, if any.

Must match ordering in rs_loglevel.
