96 CDllChecker::GetImportDataL(aFilename) reads the Image Header, Import Section |
|
97 and all import data for aFilename. If aFilename is a ROM dll, and thus has no |
|
98 import data, or if the file contains no import data for some other reason the |
|
99 function leaves with KErrGeneral. If a file is compressed, function calls |
|
100 appropriate decompression routine to inflate the import data. |
|
101 The function then calls GetDllTableL function which |
|
102 reads the first import block and enters a "for" loop. The Dll's name and Uid3 are obtained |
|
103 from CDllChecker::GetFileNameAndUid(). If the Dll name does not occur in the |
|
104 array of previously checked Dlls, CDllChecker::FindDll() is called. If the Dll |
|
105 is found,the function then calls CDllChecker::GetImportDataL on the filename acquired by |
|
106 GetFileNameAndUid()(recursive call). |
|
107 |
|
108 If the Dll contains no import data or cannot be found, or if the Uid is invalid, |
|
109 the next import is checked. |
|
110 |
|
111 The Uid3 value is checked by calling CDllChecker::CheckUid. This compares the |
|
112 Uid3 value found in the image header of the file, with that found by |
|
113 GetFileNameAndUid(). If there are any discrepancies,these are noted. |
|
114 |
|
115 Each potential import is added to the array to |
|
116 indicate its import status. |
|
117 |
|
118 CDllChecker::ListArray() lists the contents of the array when all imports |
|
119 have been checked. |
