+ Implemented Memory file system. Public functions hb_memfs*() are
availible, if HB_MEMFS_PUBLIC_API is defined.
+ Implemeted I/O driver for memory file system
; HB_IODMEM request can be used to force linking of I/O driver and
memory FS into executable.
"mem:" prefix should be used to indicate a MemFS file, ex.:
REQUEST HB_IODMEM
PROC main()
LOCAL nI
FIELD F1
DBCREATE("mem:test", {{"F1", "N", 9, 0}},, .T., "memarea")
FOR nI := 1 TO 1000
DBAPPEND(); F1 := HB_RANDOM() * 1000000
NEXT
INDEX ON F1 TAG f1
DBEVAL({|| QOUT(F1)})
DBCLOSEAREA()
DBDROP("mem:test") // Free memory resource
RETURN
; TODO: locking is not supported yet (but it is not very usefull
if MemFS is used to store of a temporary database opened in
exclusive mode).
