Detailed Description

template<typename T>
class crashpad::internal::ScopedVMMap< T >

A scoped wrapper for calls to vm_remap and vm_deallocate. Allows in-process handler to safely read and write memory (modulo its protection level) for the intermediate dump.

Note: RUNS-DURING-CRASH.

Member Function Documentation

Map() [1/2]

template<typename T>

bool crashpad::internal::ScopedVMMap< T >::Map ( const void * data, size_t count = 1 )

inline

Releases any previously mapped data and vm_remaps data.

Parameters

[in]	data	Memory to be mapped by vm_remap.
[in]	count	Length of data.

Returns

true if all data was mapped. Returns false on failure.

Map() [2/2]

template<typename T>

bool crashpad::internal::ScopedVMMap< T >::Map ( vm_address_t address, size_t count = 1 )

inline

Releases any previously mapped data and vm_remaps address.

Before reading or writing the memory, check CurrentProtection() to ensure the data is readable or writable.

Parameters

[in]	address	Address of memory to be mapped by vm_remap.
[in]	count	Length of data.

Returns

true if all of address was mapped. Returns false on failure.
