GET_FPC_CSR(3) OpenBSD Programmer's Manual (MIPS64) GET_FPC_CSR(3)NAME
get_fpc_csr, set_fpc_csr - floating-point control register access
SYNOPSIS
#include <machine/fpu.h>
int
get_fpc_csr();
int
set_fpc_csr(int csr);
DESCRIPTION
The get_fpc_csr() function returns the curent value of the floating-point
control register. The set_fpc_csr() function replaces the value of the
floating-point control register with csr and returns the previous value.
These functions are provided for IRIX compatibility, and should only be
used to control the value of the FPCSR_FS bit in the floating-point
control register. Portable code should use the fpgetmask(3),
fpgetround(3), fpgetsticky(3), fpsetmask(3), fpsetround(3), and
fpsetsticky(3) functions to inquire or alter the floating-point control
register.
RETURN VALUES
The get_fpc_csr() and set_fpc_csr() functions return the (previous) value
of the floating-point control register.
