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.
