NAME

       kcapi_kpp_keygen_aio - generate a public key (asynchronous one shot)

SYNOPSIS

       ssize_t kcapi_kpp_keygen_aio(struct kcapi_handle * handle, struct iovec * outiov, size_t iovlen,
                                    int access);

ARGUMENTS

       handle
           [in] cipher handle

       outiov
           [out] head of scatter-gather list of the destination buffers filled with the generated public key

       iovlen
           [in] number of scatter-gather list entries

       access
           [in] kernel access type (KCAPI_ACCESS_HEURISTIC - use internal heuristic for fastest kernel access;
           KCAPI_ACCESS_VMSPLICE - use vmsplice access; KCAPI_ACCESS_SENDMSG - sendmsg access)

DESCRIPTION

       The individual scatter-gather list entries are processed with separate invocations of the the given
       cipher.

       The memory should be aligned at the page boundary using posix_memalign(sysconf(_SC_PAGESIZE)), If it is
       not aligned at the page boundary, the vmsplice call may not send all data to the kernel.

       return number of bytes verify upon success; a negative errno-style error code if an error occurred
