Detailed Description

A memory region mapped from another Mach task.

The mapping is maintained until this object is destroyed.

Member Function Documentation

data()

const void * crashpad::ProcessMemoryMac::MappedMemory::data ( ) const

inline

Returns a pointer to the data requested by the user.

This is the value of the vm_address + user_offset parameters passed to the constructor, casted to const void*.

ReadCString()

bool crashpad::ProcessMemoryMac::MappedMemory::ReadCString	(	size_t	offset,
		std::string *	string ) const

Reads a NUL-terminated C string from the mapped region.

This method will read contiguous memory until a NUL terminator is found.

Parameters

[in]	offset	The offset into data() of the string to be read.
[out]	string	The string, whose contents begin at data() and continue up to a NUL terminator.

Returns

true on success, with string set appropriately. If offset is greater than or equal to the user_size constructor parameter, or if no NUL terminator was found in data() after offset, returns false with an appropriate warning logged.
