P99_THROW_CALL_RANGE #define P99_THROW_CALL_RANGE (   F,   ...  ) Value: P00_THROW_CALL_RANGE_ \ (F, \ (P99_SER(P00_THROW_CALL_RANGE_CASE, P99_STD_REAL_TYPES)), \ __VA_ARGS__) Wrap a function call to F such that it throws an error on failure. Many functions in the C and POSIX standards set errno to ERANGE to signal an under- or overflow. This wrapper makes this transparent such that it ensures that errno is always checked, and if an error occurs a value is thrown. If the error is ERANGE the value of INT_MAX is thrown for an overflow and INT_MIN for a negative overflow. If the return type of F is a floating point type ERANGE could also be set for a value that is too close to 0. In that case ERANGE is thrown directly. If errno has another non-zero value that value is thrown. Returns the value of the function call if the call was successful. Never returns if it wasn't. See also P99_THROW_CALL_NEG for a similar macro that checks if the return value is negative P99_THROW_CALL_VOIDP for a similar macro that checks a pointer return value Remarks This is only implemented for the real arithmetic types by means of a type generic macro. argument 0 maybe evaluated several times for its type but only once for its value argument 1 maybe evaluated several times for its type but only once for its value argument 2 maybe evaluated several times for its type but only once for its value argument 3 maybe evaluated several times for its type but only once for its value argument 4 maybe evaluated several times for its type but only once for its value Definition at line 249 of file p99_try.h.
