Detailed Description

Accesses information about another process, identified by a process ID.

Member Function Documentation

AbortMessage()

const std::string & crashpad::ProcessReaderLinux::AbortMessage

(

)

Returns

On Android, the abort message that was passed to android_set_abort_message(). This is only available on Q or later.

CPUTimes()

bool crashpad::ProcessReaderLinux::CPUTimes	(	timeval *	user_time,
		timeval *	system_time ) const

Determines the target process’ execution time.

Parameters

[out]	user_time	The amount of time the process has executed code in user mode.
[out]	system_time	The amount of time the process has executed code in system mode.

Returns

true on success, false on failure, with a warning logged. On failure, user_time and system_time will be set to represent no time spent executing code in user or system mode.

Initialize()

bool crashpad::ProcessReaderLinux::Initialize

(

PtraceConnection *

connection

)

Initializes this object.

This method must be successfully called before calling any other method in this class and may only be called once.

Parameters

[in]

connection

A PtraceConnection to the target process.

Returns

true on success. false on failure with a message logged.

Modules()

const std::vector< ProcessReaderLinux::Module > & crashpad::ProcessReaderLinux::Modules

(

)

Returns

The modules loaded in the process. The first element (at index 0) corresponds to the main executable.

StartTime()

bool crashpad::ProcessReaderLinux::StartTime

(

timeval *

start_time

)

const

Determines the target process’ start time.

Parameters

[out]

start_time

The time that the process started.

Returns

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