| | | | | importRVAMaxSize or importRVASize for the mapping size. Make sure to map never more than the section size. Change comments accordingly.

| | | | | | | | | | | | size from start of import RVA table to end of section. (find_first_notloaded_dll): Take big executables into account. Use offset and size computation as in hook_or_detect_cygwin, just simpler. (hook_or_detect_cygwin): Return NULL rather than false througout. Change computation of required mapping size to take non-gcc compilers into account. Explain the differences and what we do against them. Don't alloca buf if fn is NULL. Never use buf if fn is NULL. Fix name and address in previous ChangeLog entry.
* * hookapi.cc (hook_or_detect_cygwin): Take additional handleCorinna Vinschen2011-10-251-4/+34
