GetHandlerCredentials()

bool crashpad::ExceptionHandlerClient::GetHandlerCredentials

(

ucred *

creds

The handler process' credentials, valid if this method returns true.

Returns

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

RequestCrashDump()

(

const ExceptionHandlerProtocol::ClientInformation &

)

Request a crash dump from the ExceptionHandlerServer.

This method blocks until the crash dump is complete.

Parameters

[in]

info

Information about this client.

Returns

0 on success or an error code on failure.

SetCanSetPtracer()

void crashpad::ExceptionHandlerClient::SetCanSetPtracer

(

bool

can_set_ptracer

)

Enables or disables SetPtracer().

Parameters

[in]

can_set_ptracer

Whether SetPtracer should be enabled.

SetPtracer()

int crashpad::ExceptionHandlerClient::SetPtracer

(

pid_t

pid

)

Uses prctl(PR_SET_PTRACER, ...) to set the process with process ID pid as the ptracer for this process.

Parameters
