Methods for sending Linux / C udp

The only way to send UDP packets to C is to use send / sendo / write / ....

The problem is that for each package I need to make a new call from user space.

Does anyone know if there is a function that allows something like

send_packets (int socket, const char * buffer, int packetSize)

What automatically splits the data in the buffer into packets of packet size (for example, 1472), and then sends them as UDP packets?

thank
