###Here is the errors I am getting. Below the error is the code I wrote, any help would be incredibly appreciated.!! Thanks!
Can someone explained by I am getting implicit warning for malloc and Malloc_Define, I included the header files. I also would like to know how to fix the errors . Thanks.!
####Here is the code for my file which I include some kernel space files.
