Member Function Documentation

Initialize()

bool crashpad::ProcStatReader::Initialize	(	PtraceConnection *	connection,
		pid_t	tid )

Initializes the reader.

This method must be successfully called before calling any other.

Parameters

[in]	connection	A connection to the process to which the target thread belongs.
[in]	tid	The thread ID to read the stat file for.

StartTime()

bool crashpad::ProcStatReader::StartTime	(	const timeval &	boot_time,
		timeval *	start_time ) const

Determines the target thread’s start time.

Parameters

[in]	boot_time	The kernel boot time.
[out]	start_time	The time that the thread started.

Returns

true on success, with start_time set. Otherwise, false with a message logged.

SystemCPUTime()

bool crashpad::ProcStatReader::SystemCPUTime

(

timeval *

system_time

)

const

Determines the time the thread has spent executing in system mode.

Parameters

[out]

system_time

The time spent executing in system mode.

Returns

true on success, with system_time set. Otherwise, false with a message logged.

UserCPUTime()

bool crashpad::ProcStatReader::UserCPUTime

(

timeval *

user_time

)

const

Determines the time the thread has spent executing in user mode.

Parameters

[out]

user_time

The time spent executing in user mode.

Returns

true on success, with user_time set. Otherwise, false with a message logged.
