error_log_print< error_log_level::ERROR >()

template<>

void error_log_print< error_log_level::ERROR >	(	const char *	fmt,
			...
	)

error_log_print< error_log_level::INFO >()

template<>

void error_log_print< error_log_level::INFO >	(	const char *	fmt,
			...
	)

error_log_print< error_log_level::WARNING >()

template<>

void error_log_print< error_log_level::WARNING >	(	const char *	fmt,
			...
	)

get_last_error_message()

const char * get_last_error_message

(

Error_message_buf

buf

)

Error handling.

Returns error message corresponding to the last Windows error given by GetLastError().

Note

Error message is overwritten by next call to get_last_error_message().

utf8_to_wchar()

wchar_t * utf8_to_wchar	(	const char *	string,
		size_t *	len
	)

Convert an utf8 string to a wide-char string.

Parameters

[in]	string	null-terminated utf8 string to be converted
[in,out]	len	length of the string to be converted or 0; on return length (in chars) of the converted string

If len is 0 then the length of the string will be computed by this function.

Returns

Pointer to a buffer containing wide-char representation or nullptr in case of error.

Note

The returned buffer must be freed with free() call.

wchar_to_utf8()

char * wchar_to_utf8	(	const wchar_t *	string,
		size_t *	len
	)

Convert a wide-char string to utf8 representation.

Parameters

[in]	string	null-terminated wide-char string to be converted
[in,out]	len	length of the string to be converted or 0; on return length (in bytes, excluding terminating null character) of the converted string

If len is 0 then the length of the string will be computed by this function.

Returns

Pointer to a buffer containing utf8 representation or nullptr in case of error.

Note

The returned buffer must be freed with free() call.

Variable Documentation

opt_auth_win_log_level

int opt_auth_win_log_level = 2

Option indicating desired level of logging.

Values:

0 - no logging 1 - log only error messages 2 - additionally log warnings 3 - additionally log info notes 4 - also log debug messages

Value of this option should be taken into account in the implementation of error_log_vprint() function (see log_client.cc).

Note: No error or debug messages are logged in production code (see logging macros in common.h).
