Function nanocbor_get_int32

pub unsafe extern "C" fn nanocbor_get_int32(
    cvalue: *mut nanocbor_value_t,
    value: *mut i32,
) -> c_int

@brief Retrieve a signed integer as int32_t from the stream

If the value at cvalue is greater than 32 bit, error is returned.

The resulting @p value is undefined if the result is an error condition

@param[in] cvalue CBOR value to decode from @param[out] value returned signed integer

@return number of bytes read @return negative on error
