Member Function Documentation

addValue() [1/2]

void anonymous_namespace{libloadplay.cpp}::Sysctls::addValue ( mib_t const &  mib, std::string const &  value  )

inline

Add a value to the sysctls map.

Parameters

mib	The mib to add the value for
value	The value to store

addValue() [2/2]

void anonymous_namespace{libloadplay.cpp}::Sysctls::addValue ( std::string const &  name, std::string const &  value  )

inline

Add a value to the sysctls map.

Parameters

name	The symbolic name of the mib to add the value for
value	The value to store

getBaseMib()

const mib_t& anonymous_namespace{libloadplay.cpp}::Sysctls::getBaseMib ( char const *const  name ) const

inline

Retrieves the base mib for a given mib name.

E.g. the base mib for "dev.cpu.0.freq" is the mib for "dev.cpu.%d.freq".

Parameters

name	The MIB name

Returns

The MIB of the base name

getMib()

const mib_t& anonymous_namespace{libloadplay.cpp}::Sysctls::getMib ( char const *const  name ) const

inline

Returns a mib for a given symbolic name.

Parameters

name	The MIB name

Returns

The MIB

operator[]() [1/2]

SysctlValue& anonymous_namespace{libloadplay.cpp}::Sysctls::operator[] ( char const *const  name )

inline

Returns a reference to a sysctl value container.

Parameters

name	The MIB name to return the reference for

Returns

A SysctlValue reference

operator[]() [2/2]

SysctlValue& anonymous_namespace{libloadplay.cpp}::Sysctls::operator[] ( mib_t const &  mib )

inline

Returns a reference to a sysctl value container.

Parameters

mib	The MIB to return the reference for

Returns

A SysctlValue reference

        {{1007, -1},           {CTLTYPE_INT,    "-1"}},
    }

Maps mib → (type, value).
