Detailed Description

Accesses information about mapped memory in another process.

The target process must be stopped to guarantee correct mappings. If the target process is not stopped, mappings may be invalid after the return from Initialize(), and even mappings existing at the time Initialize() was called may not be found.

Member Function Documentation

FindMapping()

const MemoryMap::Mapping * crashpad::MemoryMap::FindMapping

(

LinuxVMAddress

address

)

const

Returns

The Mapping containing address or nullptr if no match is found. The caller does not take ownership of this object. It is scoped to the lifetime of the MemoryMap object that it was obtained from.

FindMappingWithName()

const MemoryMap::Mapping * crashpad::MemoryMap::FindMappingWithName

(

const std::string &

name

)

const

Returns

The Mapping with the lowest base address whose name is name or nullptr if no match is found. The caller does not take ownership of this object. It is scoped to the lifetime of the MemoryMap object that it was obtained from.

Initialize()

bool crashpad::MemoryMap::Initialize

(

pid_t

pid

)

Initializes this object with information about the mapped memory regions in the process whose ID is pid.

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

Parameters

[in]

pid

The process ID to obtain information for.

Returns

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