I'm using the VRT schema to open a raw binary image file. I can successfully access the image data by creating a VRT file with the necessary metadata, and then perform GDALOpen using the filename of the VRT file. Is there a clean way to just create the VRT metadata file in memory, instead of having to create a VRT file on disk?
Dan, I believe the VRT driver is unusual in that it allows passing the entire VRT XML contents as the filename to GDALOpen() instead of it being a file on disk. If the driver did not have this specific capacity, you could also use the /vsimem/ pseudo-filesystem handling to create the file in memory but have it appear to be on disk to most of the GDAL software.
