// Send a binary encoded 'picture' message to the socket (or actor). This
// method is similar to zsock_send, except the arguments are encoded in a
// binary format that is compatible with zproto, and is designed to reduce
// memory allocations. The pattern argument is a string that defines the
// type of each argument. Supports these argument types:
//
// pattern C type zproto type:
// 1 uint8_t type = "number" size = "1"
// 2 uint16_t type = "number" size = "2"
// 4 uint32_t type = "number" size = "3"
// 8 uint64_t type = "number" size = "4"
// s char *, 0-255 chars type = "string"
// S char *, 0-2^32-1 chars type = "longstr"
// c zchunk_t * type = "chunk"
// f zframe_t * type = "frame"
// u zuuid_t * type = "uuid"
// m zmsg_t * type = "msg"
// p void *, sends pointer value, only over inproc
//
// Does not change or take ownership of any arguments. Returns 0 if
// successful, -1 if sending failed for any reason.
