Function Documentation

◆ print_sysctls()

void anonymous_namespace{loadrec.cpp}::print_sysctls ( )

Print the sysctls.

◆ read_args()

void anonymous_namespace{loadrec.cpp}::read_args	(	int const	argc,
		char const *const	argv[]
	)

Parse command line arguments.

Parameters

argc,argv The command line arguments

◆ run()

void anonymous_namespace{loadrec.cpp}::run ( )

Report the load frames.

This prints the time in ms since the last frame and the cp_times growth as a space separated list.

◆ verbose()

template<typename... MsgTs>

void anonymous_namespace{loadrec.cpp}::verbose ( MsgTs &&... msg )

inline

Outputs the given printf style message on stderr if g.verbose is set.

Template Parameters

MsgTs The message argument types

Parameters

msg	The message to output

◆ FEATURES

constexpr const flag_t anonymous_namespace{loadrec.cpp}::FEATURES

constexpr

Initial value:

{
    1_FREQ_TRACKING
}

The set of supported features.

This value is stored in load recordings to allow loadplay to correctly interpret the data.
