Traverses a STREAMS module's linked list of open streams.
#include <pse/mi.h> #include <sys/stream.h>
caddr_t mi_next_ptr (Origin) caddr_t Origin;
The mi_next_ptr utility traverses a module's linked list of open streams. The Origin argument specifies the address of a per-instance list item, and the return value indicates the address of the next item. The first time the mi_next_ptr utility is called, the Origin parameter should be initialized with the value of the static pointer which was passed to the mi_open_comm utility. Subsequent calls to the mi_next_ptr utility should pass the address which was returned by the previous call, until a NULL address is returned, indicating that the end of the queue has been reached.
Note: The stream.h header file must be the last included header file of each source file using the stream library.
|Origin||Specifies the address of the current list item being examined.|
The mi_next_ptr utility returns the address of the next list item, or NULL if the end of the list has been reached.
The mi_next_ptr utility is part of STREAMS kernel extensions.
