WLC_SET_VAR takes a NULL-terminated ASCII string name followed by an optional value The name of the IOCTL (WLC_SET_TXANT) used in the example usage of APIs could be located in 43xxx_Wi-Fi/test/wl_tool/chip_number/test/common/include/devctrl_if/wlioctl_defs.h. A sample application i...
This IOCTL is sent to file system filter drivers, file system drivers, and other device drivers (storage filter drivers and storage drivers, for example) located below the file systems. When a file system such as NTFS receives IOCTL_VOLSNAP_FLUSH_AND_HOLD_WRITES, the file system should flush...
This requires two pairs of messages (request and response) following receipt of theM_IOCTLmessage: the firstcopyin(9F)s the structure (address) and the secondcopyin(9F)the buffer (address.ad.addr). Two states are maintained and processed in this example:GETSTRUCTis for copying in the address...

lpdoioctl illustrates driver M_IOCTL processing, which also applies to modules. In this example, only one command is recognized, SET_OPTIONS. ioc_count contains the number of user-supplied data bytes. For this example, ioc_count must equal the size of a short. ...
The name-based operation that resulted in the prefix resolution is routed to the provider that claims the prefix. If successful, MUP ensures that subsequent handle-based operations (IRP_MJ_READ and IRP_MJ_WRITE, for example) go to the same provider completely bypassing MUP. ...
