NAME

6       im_mmapinrw  -  memory  maps  a  VASARI image file  with read and write
7       access
8

SYNOPSIS

10       #include <vips/vips.h>
11
12       IMAGE *im_mmapinrw(file_name)
13       char *file_name;
14

DESCRIPTION

16       im_mmapinrw(3) works exactly as im_mmapin but the entered file_name  is
17       memory mapped with read and write permissions.  This is useful for some
18       applications, like writing lines onto an existing file.  Since the user
19       might  change accidentally the context of the original file, great care
20       should taken when handling a file with this routine.
21
22       im_open(3) is generally more convenient.
23

RETURN VALUE

25       The function returns the image descriptor on success and NULL on error.
26

SEE ALSO

28       im_close(3), im_open(3), im_makerw(3).
