.TH IM_MMAPINRW 3 "22 April 1991"
|
|
.SH NAME
|
|
im_mmapinrw \- memory maps a VASARI image file with read and write access
|
|
.SH SYNOPSIS
|
|
.B #include <vips/vips.h>
|
|
|
|
.B IMAGE *im_mmapinrw(file_name)
|
|
.br
|
|
.B char *file_name;
|
|
.SH DESCRIPTION
|
|
.B im_mmapinrw(3)
|
|
works exactly as im_mmapin but the entered file_name is memory mapped
|
|
with read and write permissions. This is useful for some applications,
|
|
like writing lines onto an existing file. Since
|
|
the user might change accidentally the context of the original file,
|
|
great care should taken when handling a file with this routine.
|
|
|
|
im_open(3) is generally more convenient.
|
|
.SH RETURN VALUE
|
|
The function returns the image descriptor on success and NULL on error.
|
|
.SH SEE\ ALSO
|
|
im_close(3), im_open(3), im_makerw(3).
