4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Provides services to load and relocate a PE/COFF image.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The PE/COFF Loader Library abstracts the implementation of a PE/COFF loader for
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync IA-32, x86, IPF, and EBC processor types. The library functions are memory-based
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync and can be ported easily to any environment.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync// Return status codes from the PE/COFF Loader services
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Reads contents of a PE/COFF image.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync A function of this type reads contents of the PE/COFF image specified by FileHandle. The read
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync operation copies ReadSize bytes from the PE/COFF image starting at byte offset FileOffset into
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the buffer specified by Buffer. The size of the buffer actually read is returned in ReadSize.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync If FileOffset specifies an offset past the end of the PE/COFF image, a ReadSize of 0 is returned.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync A function of this type must be registered in the ImageRead field of a PE_COFF_LOADER_IMAGE_CONTEXT
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync structure for the PE/COFF Loader Library service to function correctly. This function abstracts access
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync to a PE/COFF image so it can be implemented in an environment specific manner. For example, SEC and PEI
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync environments may access memory directly to read the contents of a PE/COFF image, and DXE or UEFI
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync environments may require protocol services to read the contents of PE/COFF image

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Reads contents of a PE/COFF image from a buffer in system memory.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This is the default implementation of a PE_COFF_LOADER_READ_FILE function
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync that assumes FileHandle pointer to the beginning of a PE/COFF image.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function reads contents of the PE/COFF image that starts at the system memory
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync address specified by FileHandle. The read operation copies ReadSize bytes from the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync PE/COFF image starting at byte offset FileOffset into the buffer specified by Buffer.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The size of the buffer actually read is returned in ReadSize.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync If FileHandle is NULL, then ASSERT().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync If ReadSize is NULL, then ASSERT().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync If Buffer is NULL, then ASSERT().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param FileHandle The pointer to base of the input stream
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param FileOffset Offset into the PE/COFF image to begin the read operation.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param ReadSize On input, the size in bytes of the requested read operation.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync On output, the number of bytes actually read.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Buffer Output buffer that contains the data read from the PE/COFF image.
404cc3d8ee7f345150f9d3ea57e56714adcca56avboxsync @retval RETURN_SUCCESS The data is read from FileOffset from the Handle into
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the buffer.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Reapply fixups on a fixed up PE32/PE32+ image to allow virutal calling at EFI
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function reapplies relocation fixups to the PE/COFF image specified by ImageBase
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync and ImageSize so the image will execute correctly when the PE/COFF image is mapped
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync to the address specified by VirtualImageBase. RelocationData must be identical
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync to the FiuxupData buffer from the PE_COFF_LOADER_IMAGE_CONTEXT structure
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync after this PE/COFF image was relocated with PeCoffLoaderRelocateImage().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Note that if the platform does not maintain coherency between the instruction cache(s) and the data
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync cache(s) in hardware, then the caller is responsible for performing cache maintenance operations
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync prior to transferring control to a PE/COFF image that is loaded using this library.
404cc3d8ee7f345150f9d3ea57e56714adcca56avboxsync @param ImageBase The base address of a PE/COFF image that has been loaded
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync and relocated into system memory.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param VirtImageBase The request virtual address that the PE/COFF image is to
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync be fixed up for.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param ImageSize The size, in bytes, of the PE/COFF image.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param RelocationData A pointer to the relocation data that was collected when the PE/COFF
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync image was relocated using PeCoffLoaderRelocateImage().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Unloads a loaded PE/COFF image from memory and releases its taken resource.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Releases any environment specific resources that were allocated when the image
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync specified by ImageContext was loaded using PeCoffLoaderLoadImage().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync For NT32 emulator, the PE/COFF image loaded by system needs to release.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync For real platform, the PE/COFF image loaded by Core doesn't needs to be unloaded,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync this function can simply return RETURN_SUCCESS.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync If ImageContext is NULL, then ASSERT().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param ImageContext Pointer to the image context structure that describes the PE/COFF
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync image to be unloaded.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval RETURN_SUCCESS The PE/COFF image was unloaded successfully.
