+.SH NAME
+feholdexcept \- save current floating-point environment
+.SH SYNOPSIS
+.LP
+\fB#include <fenv.h>
+.br
+.sp
+int feholdexcept(fenv_t *\fP\fIenvp\fP\fB);
+.br
+\fP
+.SH DESCRIPTION
+.LP
+The \fIfeholdexcept\fP() function shall save the current floating-point
+environment in the object pointed to by \fIenvp\fP,
+clear the floating-point status flags, and then install a non-stop
+(continue on floating-point exceptions) mode, if available, for
+all floating-point exceptions.
+.SH RETURN VALUE
+.LP
+The \fIfeholdexcept\fP() function shall return zero if and only if
+non-stop floating-point exception handling was successfully
+installed.
+.SH ERRORS
+.LP
+No errors are defined.
+.LP
+\fIThe following sections are informative.\fP
+.SH EXAMPLES
+.LP
+None.
+.SH APPLICATION USAGE
+.LP
+None.
+.SH RATIONALE
+.LP
+The \fIfeholdexcept\fP() function should be effective on typical IEC\ 60559:1989
+standard implementations which have the
+default non-stop mode and at least one other mode for trap handling
+or aborting. If the implementation provides only the non-stop
+mode, then installing the non-stop mode is trivial.
+.SH FUTURE DIRECTIONS
+.LP
+None.
