|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
library provides an emulation of the OSS (Linux) audio
|
|
|
|
|
interface.
|
|
|
|
|
.Pp
|
|
|
|
|
Use the native interface for new programs and the emulation
|
|
|
|
|
library only for porting programs.

.Sh BUGS
|
1999-07-02 19:37:33 +04:00
|
|
|
The emulation uses an #define for
|
1997-10-29 03:31:01 +03:00
|
|
|
.Va ioctl()
|
|
|
|
|
so some obscure programs
|
1997-10-16 21:46:28 +04:00
|
|
|
can fail to compile.
|
|
|
|
|
.Pp
|
|
|
|
|
The emulation is incomplete.
|
1997-10-29 03:31:01 +03:00
|
|
|
.Pp
|
1999-07-02 19:37:33 +04:00
|
|
|
The emulation only covers
|
1997-10-29 03:31:01 +03:00
|
|
|
.Va ioctl() ,
|
|
|
|
|
there are other differences as well. E.g., on a write
|
|
|
|
|
that would block in non-blocking mode Linux returns
|
|
|
|
|
.Dv EINTR
|
|
|
|
|
whereas
|
|
|
|
|
.Nx 1.3
|
|
|
|
|
returns
|
|
|
|
|
.Dv EWOULDBLOCK .
