Routine Description:
|
|
|
|
Support routine for the PE/COFF Loader that reads a buffer from a PE/COFF file
|
|
|
|
Arguments:
|
|
|
|
FileHandle - The handle to the PE/COFF file
|
|
|
|
FileOffset - The offset, in bytes, into the file to read
|
|
|
|
ReadSize - The number of bytes to read from the file starting at FileOffset
|
|
|
|
Buffer - A pointer to the buffer to read the data into.
|
|
|
|
Returns:
|
|
|
|
EFI_SUCCESS - ReadSize bytes of data were read into Buffer from the PE/COFF file starting at FileOffset
