◆ Clear()

void SBMemoryRegionInfo::Clear ( )

Definition at line 63 of file SBMemoryRegionInfo.cpp.

References LLDB_INSTRUMENT_VA, and m_opaque_up.

◆ GetDescription()

bool SBMemoryRegionInfo::GetDescription ( lldb::SBStream &  description)

Definition at line 163 of file SBMemoryRegionInfo.cpp.

References LLDB_INSTRUMENT_VA, m_opaque_up, lldb_private::Stream::Printf(), and lldb::SBStream::ref().

◆ GetDirtyPageAddressAtIndex()

addr_t SBMemoryRegionInfo::GetDirtyPageAddressAtIndex ( uint32_t  idx)

Returns the address of a memory page that has been modified in this region.

Returns
Returns the address for his dirty page in the list. If this memory region does not have a dirty page list, LLDB_INVALID_ADDRESS is returned.

Definition at line 145 of file SBMemoryRegionInfo.cpp.

References LLDB_INSTRUMENT_VA, LLDB_INVALID_ADDRESS, and m_opaque_up.

◆ GetName()

const char * SBMemoryRegionInfo::GetName ( )

Returns the name of the memory region mapped at the given address.

Returns
In case of memory mapped files it is the absolute path of the file otherwise it is a name associated with the memory region. If no name can be determined the returns nullptr.

Definition at line 121 of file SBMemoryRegionInfo.cpp.

References LLDB_INSTRUMENT_VA, and m_opaque_up.

◆ GetNumDirtyPages()

uint32_t SBMemoryRegionInfo::GetNumDirtyPages ( )

Returns the number of modified pages – dirty pages – in this memory region.

Returns
The number of dirty page entries will be returned. If there are no dirty pages in this memory region, 0 will be returned. 0 will also be returned if the dirty page list is not available for this memory region – you must use HasDirtyMemoryPageList() to check for that.

Definition at line 133 of file SBMemoryRegionInfo.cpp.

References LLDB_INSTRUMENT_VA, and m_opaque_up.

◆ GetPageSize()

int SBMemoryRegionInfo::GetPageSize ( )

Returns the size of a memory page in this region.

Returns
Returns the size of the memory pages in this region, or 0 if this information is unavailable.

Definition at line 157 of file SBMemoryRegionInfo.cpp.

References LLDB_INSTRUMENT_VA, and m_opaque_up.

◆ GetRegionBase()

lldb::addr_t SBMemoryRegionInfo::GetRegionBase ( )

Get the base address of this memory range.

Returns

References LLDB_INSTRUMENT_VA, and m_opaque_up.

◆ GetRegionEnd()

lldb::addr_t SBMemoryRegionInfo::GetRegionEnd ( )

Get the end address of this memory range.

Returns
The base address of this memory range.

Definition at line 91 of file SBMemoryRegionInfo.cpp.

References LLDB_INSTRUMENT_VA, and m_opaque_up.

◆ HasDirtyMemoryPageList()

bool SBMemoryRegionInfo::HasDirtyMemoryPageList ( )

Returns whether this memory region has a list of memory pages that have been modified – that are dirty.

Returns
True if the dirty page list is available.
