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.

| 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.

| 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.
