sounds by mdl

The following virtual memory can be understood as logical memory, because I think only in this way can we talk about everything below. The following "not paging" indicates that the page is not encoded. The following is the MDL struct (I am very depressed.

MDL (Memory Descriptor List) refers to the Memory Descriptor table, which contains the starting address, owner process, number of bytes, and flag of the Memory region. The MDL structure is defined in ntddk. h. The specific structure is as follows: Typedef struct _ MDL { Struct _ MDL * Next; CSHORT Size; CSHORT MdlFlags

MDL (memory descriptor list) is usually used to describe the location of the physical memory corresponding to VA. Generally, the content that can be accessed by the driver includes next and mdlflags. Wdk defines several common macros to access some variables in MDL, including: MmgetmdlvirtualaddressReturns the virtual memory address of the buffer.// Virtual Memory Address MmgetmdlbytecountReturns the
