Function Documentation

static void _fr_logging_free ( void *  arg )

static

Definition at line 142 of file log.c.

Here is the caller graph for this function:

void fr_canonicalize_error	(	TALLOC_CTX *	ctx,
		char **	sp,
		char **	text,
		ssize_t	slen,
		char const *	msg
	)

Canonicalize error strings, removing tabs, and generate spaces for error marker.

Note

talloc_free must be called on the buffer returned in spaces and text

Used to produce error messages such as this:

 I'm a string with a parser # error
                            ^ Unexpected character in string

With code resembling this:

ERROR("%s", parsed_str);
ERROR("%s^ %s", space, text);

Todo:

merge with above function (radlog_request_marker)

Parameters

sp	Where to write a dynamically allocated buffer of spaces used to indent the error text.
text	Where to write the canonicalized version of msg (the error text).
ctx	to allocate the spaces and text buffers in.
slen	of error marker. Expects negative integer value, as returned by parse functions.
msg	to canonicalize.

Here is the caller graph for this function:

char const* fr_strerror

(

void

)

Get the last library error.

Will only return the last library error once, after which it will return a zero length string.

Returns

library error or zero length string.

Definition at line 212 of file log.c.

Here is the caller graph for this function:

void fr_strerror_printf	(	char const *	fmt,
			...
	)

Log to thread local error buffer.

Parameters

fmt	printf style format string. If NULL sets the 'new' byte to false, effectively clearing the last message.

Here is the caller graph for this function:

char const* fr_syserror

(

int

num

)

Guaranteed to be thread-safe version of strerror.

Parameters

num	errno as returned by function or from global errno.

Returns

local specific error string relating to errno.

fr_thread_local_setup	(	char *	,
		fr_strerror_buffer

POSIX-2008 errno macros.

Non-POSIX macros may be added, but you must check they're defined.
