1/* 2 * Attribution notice: Rainbow have generously allowed me to reproduce the 3 * necessary definitions here from their API. This means the support can 4 * build independently of whether application builders have the API or 5 * hardware. This will allow developers to easily produce software that has 6 * latent hardware support for any users that have accelertors installed, 7 * without the developers themselves needing anything extra. I have only 8 * clipped the parts from the CryptoSwift header files that are (or seem) 9 * relevant to the CryptoSwift support code. This is simply to keep the file 10 * sizes reasonable. [Geoff] 11 */ 12 13/* 14 * NB: These type widths do *not* seem right in general, in particular 15 * they're not terribly friendly to 64-bit architectures (unsigned long) will 16 * be 64-bit on IA-64 for a start. I'm leaving these alone as they agree with 17 * Rainbow's API and this will only be called into question on platforms with 18 * Rainbow support anyway! ;-) 19 */ 20 21#ifdef __cplusplus 22extern "C" { 23#endif /* __cplusplus */ 24 25 typedef long SW_STATUS;
