316 @function buf_map
319 buf_map() just returns the address at which data was mapped by but_getblk(). For a B_CLUSTER buffer, i.e. an iobuf
322 Otherwise, the buffer was created with buf_alloc() and buf_setupl() was subsequently called; buf_map()
325 to tear down the mapping. NOTE: buf_map() does not set the buffer data pointer; this must be done with buf_setdataptr().
330 errno_t buf_map(buf_t, caddr_t *);
340 buf_setupl() was subsequently called; buf_map() created the mapping. In this case, buf_unmap() will
495 be set with buf_setdataptr(). See buf_map().
611 A subsequent call to buf_map() will map the UPL and give back the address at which data
672 set up using buf_setdataptr() or buf_setupl()/buf_map().
