Detailed Description

A COFF section.

Member Data Documentation

offset_t COFF::COFFFormat::Section::physical_address = 0

The physical address of the section (expected to be identical to the virtual address) (COFF name: s_paddr)

For PE/COFF, this field is reinterpreted as the size of the section in memory
