/** | |||||

* Returns: 1: signature created | |||||
* 0: the nonce generation function failed, or the private key was | |||||
* invalid. | |||||
* Args: ctx: pointer to a context object, initialized for signing | |||||
* (cannot be NULL) | |||||
* Out: sig64: pointer to a 64-byte array where the signature will be | |||||
* placed (cannot be NULL) | |||||
* In: msg32: the 32-byte message hash being signed (cannot be NULL) | |||||
* seckey: pointer to a 32-byte secret key (cannot be NULL) | |||||
* pubkey: the public key to sign with (cannot be NULL) | |||||
* noncefp:pointer to a nonce generation function. If NULL, | |||||
* secp256k1_nonce_function_default is used | |||||
