The \fIexcepts\fR argument specifies the floating-point status flags to be queried. .SH RETURN VALUES .sp .LP The \fBfetestexcept()\fR function returns the value of the bitwise-inclusive OR of the floating-point exception macros corresponding to the currently set floating-point exceptions included in \fIexcepts\fR. .SH ERRORS .sp .LP No errors are defined. .SH EXAMPLES .LP \fBExample 1\fR Example using \fBfetestexcept()\fR .sp .LP 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 .in +2 .nf #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(); /* ... */ } .fi .in -2 .sp .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
