[in,out]lhsthe output stream into which rhs is written.
[in]rhsthe object to be written into lhs.
Return values
referenceto the output stream.

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]thdThe connection thread to which to send the error
[in]errThe high-level error code in InnoDB caused by low-level errno
[in]contextThe 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]thdThe connection thread to which to send the warning
[in]errThe high-level error code in InnoDB caused by low-level errno
[in]contextThe 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]fmtThe 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]fmtThe format string
[in]headThe first argument
[in]tailOthers (perhaps none) arguments
Returns
true if and only if the format specifiers found in fmt correspond to types of head, tail...
