NAME
       mmap_read - memory map a file for reading

SYNTAX
       #include <mmap.h>

       char* mmap_read(const char* filename,size_t* filesize);

DESCRIPTION
       mmap_read  opens  filename  for	reading,  maps	the whole file into memory, closes the file, writes the length of the file to filesize and
       returns a pointer to the mapped file.

       The file is unmapped by the operating system if the process  terminates.   It  can  also  be  manually  unmapped  by  calling  munmap  from
       <sys/mman.h>.

       If the file could not be opened or mapped, (void*)0 is returned.
