Detailed Description

Discrete, contiguous part of the source's data.

This class is purely abstract and subclasses of DataSource are expected to subclass it to implement a segment particular to their needs.

Member Function Documentation

virtual unsigned elftosb::DataSource::Segment::getData ( unsigned  offset, unsigned  maxBytes, uint8_t *  buffer  )

pure virtual

Gets all or a portion of the segment's data.

The data is copied into buffer. Up to maxBytes bytes may be copied, so buffer must be at least that large.

Parameters

offset	Index of the first byte to start copying from.
maxBytes	The maximum number of bytes that can be returned. buffer must be at least this large.
buffer	Pointer to buffer where the data is copied.

Returns

The number of bytes copied into buffer.

Implemented in elftosb::MemoryImageDataSource::TextSegment, elftosb::IVTDataSource, elftosb::UnmappedDataSource, elftosb::ELFSourceFile::ELFDataSource::ProgBitsSegment, and elftosb::DataSource::PatternSegment.
