Function Documentation

long qpid::sys::SystemInfo::concurrency

(

)

Estimate available concurrency, e.g.

number of CPU cores. -1 means estimate not available on this platform.

bool qpid::sys::SystemInfo::getLocalHostname

(

Address &

address

)

Get the local host name and set it in the specified.

Returns false if it can't be obtained and sets errno to any error value.

void qpid::sys::SystemInfo::getLocalIpAddresses	(	uint16_t	port,
		std::vector< Address > &	addrList
	)

uint32_t qpid::sys::SystemInfo::getParentProcessId

(

)

Get the process ID of the parent of the current process.

uint32_t qpid::sys::SystemInfo::getProcessId

(

)

Get the process ID of the current process.

std::string qpid::sys::SystemInfo::getProcessName

(

)

Get the name of the current process (i.e.

the name of the executable)

void qpid::sys::SystemInfo::getSystemId	(	std::string &	osName,
		std::string &	nodeName,
		std::string &	release,
		std::string &	version,
		std::string &	machine
	)

Retrieve system identifiers and versions.

This is information that can generally be retrieved via POSIX uname().

Parameters:

	osName	Receives the OS name; e.g., GNU/Linux or Windows
	nodeName	Receives the nodename. This may or may not match the set hostname from getLocalHostname().
	release	Receives the OS release identifier.
	version	Receives the OS release version (kernel, build, sp, etc.)
	machine	Receives the hardware type.
