Thank you
-I added a struct (*DeviceExtension) who contain a membre : buffer[…]. (
DeviceExtension : member of DeviceObject create with IOcreatedevice.
All preserved in some Global struct. )
-
Inside Protocolbinhandler : , in beginnig I try to write in this
buffer a message like “hello from protocolbindhandler”. -
Inside fonction MyRead (irp_mj_read) I try to read this message from
buffer[…].
Dramatically : buffer is empty
No man’s Land.
Thank for suggest.
