Function Documentation

boost::posix_time::ptime rsc::os::currentBootTime

(

)

Return the boot time of the local machine.

The precision with which the boot time can be determined varies between platforms.

Returns

boost::posix_time::ptime encoding the boot time of the machine.

Exceptions

std::runtime_error

If determining the boot time fails.

Here is the caller graph for this function:

std::string rsc::os::currentHostId

(

)

Determine and return a unique id string of the local machine.

This unique id should not change over time but callers should still be prepared to deal with that since not all implementation can provide a constant unique id.

Returns

A unique id string for the local machine.

Exceptions

std::runtime_error

If the unique id cannot be determined.

Here is the call graph for this function:

std::string rsc::os::currentHostname

(

)

Determine and return the hostname of the local machine.

Note that the hostname can change over time.

Returns

The current hostname of the local machine.

Exceptions

std::runtime_error

If the hostname cannot be determined.

std::string rsc::os::currentMachineType

(

)

Determine and return the machine type, usually CPU architecture, of the local machine.

Returns

The machine type of the local machine.

Exceptions

std::runtime_error

If the machine type cannot be determined.

Definition at line 68 of file PosixUtilities.cpp.

Here is the call graph for this function:

std::string rsc::os::currentMachineVersion

(

)

Determine and return the version within its type, usually the CPU identification string, of the local machine.

Returns

The machine version of the local machine.

Exceptions

std::runtime_error

If the machine version cannot be determined.

Definition at line 47 of file LinuxHostInfo.cpp.

std::string rsc::os::currentSoftwareType

(

)

Determine and return the type of the operating system, usually the kernel name, running on the local machine.

Returns

The software type of the local machine.

Exceptions

std::runtime_error

If the software type cannot be determined.

Definition at line 80 of file PosixUtilities.cpp.

References rsc::os::callWithUtsname().

Here is the call graph for this function:

std::string rsc::os::currentSoftwareVersion

(

)

Determine and return the version of the operating system within its type, usually the kernel version string, running on the local machine.

Returns

The software version of the local machine.

Exceptions

std::runtime_error

If the software version cannot be determined.
