+.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
+fetestexcept
+\(em test floating-point exception flags
+.SH SYNOPSIS
+.LP
+.nf
+#include <fenv.h>
+.P
+int fetestexcept(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
+\fIfetestexcept\fR()
+function shall determine which of a specified subset of the
+floating-point exception flags are currently set. The
+.IR excepts
+argument specifies the floating-point status flags to be queried.
+.SH "RETURN VALUE"
+The
+\fIfetestexcept\fR()
+function shall return the value of the bitwise-inclusive OR of the
+floating-point exception macros corresponding to the currently set
+floating-point exceptions included in
+.IR excepts .
+.SH ERRORS
+No errors are defined.
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+The following example calls function
+\fIf\fR()
+if an invalid exception is set, and then function
+\fIg\fR()
+if an overflow exception is set:
+.sp
+.RS 4
+.nf
+\fB
+#include <fenv.h>
+/* ... */
+{
+    #pragma STDC FENV_ACCESS ON
+    int set_excepts;
+    feclearexcept(FE_INVALID | FE_OVERFLOW);
+    // maybe raise exceptions
+    set_excepts = fetestexcept(FE_INVALID | FE_OVERFLOW);
+    if (set_excepts & FE_INVALID) f();
+    if (set_excepts & FE_OVERFLOW) g();
+    /* ... */
