mmap_read - memory map a file for reading
SYNTAX¶
#include <mmap.h>

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.
