.TH mmap_private 3
.SH NAME
mmap_private \- memory map a file for reading and writing
.SH SYNTAX
.B #include <mmap.h>
extern char* \fBmmap_private\fP(const char* \fIfilename\fR,unsigned long* \fIfilesize\fR);
.SH DESCRIPTION
mmap_private opens \fIfilename\fR for reading and writing, maps the
whole file into memory, closes the file, writes the length of the file
to \fIfilesize\fR and returns a pointer to the mapped file.
The file is mapped copy-on-write. Changes done to the mapped region
will not be written to disk.
The file is unmapped by the operating system if the process terminates.
It can also be manually unmapped by calling \fBmunmap\fR from
<sys/mman.h>.
