.SH "DESCRIPTION"
.PP
These functions are non-portable RTLinux extensions.
.PP
\fBpthread_attr_setfp_np\fP modifies the thread attribute
object \fIattribute\fP to allow or disallow use of the floating
point unit (FPU) in the created thread.
\fBuse_fp\fR is zero to disallow floating-point operations, or
non-zero to allow them.
The thread
attribute object \fIattr\fP first has to be initialized with
\fBpthread_attr_init(3)\fP.
.PP
\fBpthread_attr_getfp_np\fP fills the location pointed to
by \fBcpu\fR with the \fBuse_fp\fR flag from
the attribute structure.
.SH "RETURN VALUE"
.PP
All functions return 0 on success and a non-zero error code on error.
.SH "ERRORS"
.PP
No errors are defined.
.SH "NOTES"
.PP
By default, floating point operations are disallowed in RT-threads.
