Types ¶
type COFFSymbol ¶
type COFFSymbol struct {
Name [8]uint8
Value uint32
SectionNumber int16
Type uint16
StorageClass uint8
NumberOfAuxSymbols uint8
}
COFFSymbol represents single COFF symbol table record.
type COFFSymbolAuxFormat5 ¶
type COFFSymbolAuxFormat5 struct {
Size uint32
NumRelocs uint16
NumLineNumbers uint16
Checksum uint32
SecNum uint16
Selection uint8
// contains filtered or unexported fields
}
COFFSymbolAuxFormat5 describes the expected form of an aux symbol attached to a section definition symbol. The PE format defines a number of different aux symbol formats: format 1 for function definitions, format 2 for .be and .ef symbols, and so on. Format 5 holds extra info associated with a section definition, including number of relocations + line numbers, as well as COMDAT info. See https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#auxiliary-format-5-section-definitions for more on what's going on here.
