44 | This file turns a regular Windows PE image into a DLL. Because of | |
45 | the complexity of this operation, it has been broken down into a | |
46 | number of separate modules which are all called by the main function | |
47 | at the end of this file. This function is not re-entrant and is | |
48 | normally only called once, so static variables are used to reduce | |
49 | the number of parameters and return values required. | |
