Detailed Description

Generic base class which exposes information about an operating system process.

This base class is the core interface behind any OS process. It exposes methods to query for generic information about a particular process.

Subclasses implement this interface based on the mechanisms available, and can optionally expose more interfaces unique to certain process kinds.

Member Typedef Documentation

typedef pid_t llvm::sys::process::id_type

Operating system specific type to identify a process.

Note that the windows one is defined to 'unsigned long' as this is the documented type for DWORD on windows, and we don't want to pull in the Windows headers here.

Definition at line 63 of file Process.h.

Constructor & Destructor Documentation

process::~process ( )

protectedvirtual

Only specific subclasses of process objects can be destroyed.

Member Function Documentation

virtual id_type llvm::sys::process::get_id ( )

pure virtual

Get the operating system specific identifier for this process.

Implemented in llvm::sys::self_process.

self_process * process::get_self ( )

static

Get the process object for the current process.

virtual TimeValue llvm::sys::process::get_system_time ( ) const

pure virtual

Get the system time consumed by this process.

Note that this is often an approximation and may be zero on platforms where we don't have good support for the functionality.

Implemented in llvm::sys::self_process.

virtual TimeValue llvm::sys::process::get_user_time ( ) const

pure virtual

Get the user time consumed by this process.

Note that this is often an approximation and may be zero on platforms where we don't have good support for the functionality.

Implemented in llvm::sys::self_process.

virtual TimeValue llvm::sys::process::get_wall_time ( ) const

pure virtual

Get the wall time consumed by this process.

Note that this is often an approximation and may be zero on platforms where we don't have good support for the functionality.

Implemented in llvm::sys::self_process.
