| .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). |
