.ixfunc2 '&DosFunc' &func
.funcend
.desc begin
The &func function uses system call 0x2D to set the current system time.
The time information is passed in a
.kw dostime_t
structure pointed to by
.arg time.
.desc end
.return begin
The &func function returns zero if successful.
Otherwise, it returns a non-zero value and sets
.kw errno
to
.kw EINVAL
indicating that an invalid time was given.
