operator<<()

std::ostream & ib::operator<< ( std::ostream &  lhs, const hex &  rhs  )

inline

This is an overload of the global operator<< for the user defined type ib::hex.

The unsigned value held in the ib::hex wrapper class will be printed into the given output stream in hexadecimal format.

Parameters

[in,out]	lhs	the output stream into which rhs is written.
[in]	rhs	the object to be written into lhs.

Return values

reference

to the output stream.

scan_page_type()

void ib::scan_page_type	(	space_id_t	space_id,
		std::map< page_type_t, page_no_t > &	result_map
	)

send_errno_error()

void ib::send_errno_error ( THD *  thd, int  err, const std::string &  context  )

inline

Sends an error to the client about low-level errno causing high-level err in the specified context.

It is a helper to be used when a low-level IO operation has failed and set errno.

Parameters

[in]	thd	The connection thread to which to send the error
[in]	err	The high-level error code in InnoDB caused by low-level errno
[in]	context	The human-readable string explaining what was going on

send_errno_warn()

void ib::send_errno_warn ( THD *  thd, int  err, const std::string &  context  )

inline

Sends a warning to the client about low-level errno causing high-level err in the specified context.

It is a helper to be used when a low-level IO operation has failed and set errno.

Parameters

[in]	thd	The connection thread to which to send the warning
[in]	err	The high-level error code in InnoDB caused by low-level errno
[in]	context	The human-readable string explaining what was going on

verify_fmt_match() [1/2]

static bool ib::verify_fmt_match ( const char *  fmt )

inlinestatic

Verifies that the fmt format string does not require any arguments.

Parameters

[in]

fmt

The format string

Returns

true if and only if there is no format specifier inside fmt which requires passing an argument

verify_fmt_match() [2/2]

template<typename Head , typename... Tail>

static bool ib::verify_fmt_match ( const char *  fmt, Head &&  head, Tail &&...  tail  )

static

Verifies that the fmt format string contains format specifiers which match the type and order of the arguments.

Parameters

[in]	fmt	The format string
[in]	head	The first argument
[in]	tail	Others (perhaps none) arguments

Returns

true if and only if the format specifiers found in fmt correspond to types of head, tail...
