मैं अपना पुराना स्रोत कोड देखूंगा और बाद में एक कामकाजी कोड पोस्ट करूंगा जो इस सारणी को समावेशी बाध्यकारी जानकारी दोनों को डंप करेगा।
UPDATED:
यहाँ एक कोड है जो मैं अपने पुराने कार्यक्रम में से एक में शौकीन है। यह केवल 32-बिट पीई का समर्थन करता है, लेकिन इसे 64-बिट में आसानी से संशोधित किया जा सकता है। जिस तरह से आप देख सकते हैं, कि यह बाध्यकारी जानकारी भी डंप करता है। परीक्षण करने के लिए पीई को बांधें जिसे आप bind.exe के संबंध में डंप करना चाहते हैं (उदाहरण के लिए उपयोग करें, bind.exe -u -v Test.dll
)।
कोड में लगभग 1000 लाइनें शामिल हैं, इसलिए मैं इसे यहां पोस्ट नहीं कर सका। मुझे एक त्रुटि संदेश
ओह! आपका संपादन सबमिट नहीं किया जा सका क्योंकि:
- शरीर 30000 वर्णों तक सीमित है; आपने 55095
इसलिए मैंने इसे यहां रखा: http://www.ok-soft-gmbh.com/ForStackOverflow/PEInfo.c। मुझे आशा है कि कोड आपको लंबे विवरण के रूप में बेहतर तरीके से मदद करेगा।
अद्यतन 2: मुझे लगता है कि मेरा पुराना उत्तर खोज इंजन के लिए अच्छा नहीं है।
