Hi, after reading https://gdal.org/user/virtual_file_systems.html#vsistdout-standard-output-streaming I have to say I don't understand what it means.
I which cases it's used? Some example to consider? In the driver I have to do something with that? I have, copied from other, if (!STARTS_WITH(pszFilename, "/vsistdout")) and then I open the file as usual. But, what I have to do if the name starts with that? On the other hand, I am confused about the Update concept. My driver is capable of creating from zero a layer from other formats. But I haven't programmed the capacity to insert a feature in a pre-existent layer (I cannot simply add at the end of the file because de format description is a little more complicated). What I do now is OGRMiraMonLayer() <-- if Update is true, I open from zero and create a new MiraMon layer If not, I read the layer. But, there is something to take in consideration about the capacity of inserting a feature in a pre-existent layer? Thanks.
