Detailed Description

The specific class representing the current process.

The current process can both specialize the implementation of the routines and can expose certain information not available for other OS processes.

Member Function Documentation

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

virtual

Get the operating system specific identifier for this process.

Implements llvm::sys::process.

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

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.

Implements llvm::sys::process.

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

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.

Implements llvm::sys::process.

TimeValue self_process::get_wall_time ( ) const

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.

Implements llvm::sys::process.

References getElapsedWallTime().

size_t llvm::sys::self_process::page_size ( ) const

inline

Get the virtual memory page size.
