+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),
+or the interface may not be implemented on Linux.

+.SH NAME
+fegetexceptflag,
+fesetexceptflag
+\(em get and set floating-point status flags
+.SH SYNOPSIS
+.LP
+.nf
+#include <fenv.h>
+.P
+int fegetexceptflag(fexcept_t *\fIflagp\fP, int \fIexcepts\fP);
+int fesetexceptflag(const fexcept_t *\fIflagp\fP, int \fIexcepts\fP);
+.fi
+.SH DESCRIPTION
+The functionality described on this reference page is aligned with the
+ISO\ C standard. Any conflict between the requirements described here and the
+ISO\ C standard is unintentional. This volume of POSIX.1\(hy2008 defers to the ISO\ C standard.
+.P
+The
+\fIfegetexceptflag\fR()
+function shall attempt to store an implementation-defined representation
+of the states of the floating-point status flags indicated by the argument
+.IR excepts
+in the object pointed to by the argument
+.IR flagp .
+.P
+The
+\fIfesetexceptflag\fR()
+function shall attempt to set the floating-point status flags indicated
+by the argument
+.IR excepts
+to the states stored in the object pointed to by
+.IR flagp .
+The value pointed to by
+.IR flagp
+shall have been set by a previous call to
+\fIfegetexceptflag\fR()
+whose second argument represented at least those floating-point
+exceptions represented by the argument
+.IR excepts .
+This function does not raise floating-point exceptions, but only sets
+the state of the flags.
+.SH "RETURN VALUE"
+If the representation was successfully stored,
+\fIfegetexceptflag\fR()
+shall return zero. Otherwise, it shall return a non-zero value. If the
+.IR excepts
+argument is zero or if all the specified exceptions were successfully
+set,
+\fIfesetexceptflag\fR()
+shall return zero. Otherwise, it shall return a non-zero value.
+.SH ERRORS
+No errors are defined.
