E32ImageHeader Class Reference

class E32ImageHeader

Structure for an executable image's header. This is extended by E32ImageHeaderComp and E32ImageHeaderV . All executables since Symbian OS version 8.1b have an header given by class E32ImageHeaderV .

Summary of an executable image structure...

  • Header, 0..iCodeOffset-1

  • Code part, iCodeOffset..iCodeOffset+iCodeSize-1

    • .text section, 0 + iTextSize

    • Import Address Table (IAT), iText + ?

    • Export Directory, iExportDirOffset + iExportDirCount*4 (in .text Section)

  • Rest of data, iCodeOffset+iCodeSize..EOF

    • .data section, iDataOffset + iDataSize

    • Import section, iImportOffset + sizeof(E32ImportSection)+?

    • Code relocation section, iCodeRelocOffset + sizeof(E32RelocSection)+?

    • Data relocation section, iDataRelocOffset + sizeof(E32RelocSection)+?
