Functions
protocomm_t *protocomm_new(void)
Create a new protocomm instance.
This API will return a new dynamically allocated protocomm instance with all elements of the protocomm_t
structure initialized to NULL.
Return
• protocomm_t* : On success
• NULL : No memory for allocating new instance
void protocomm_delete(protocomm_t
Delete a protocomm instance.
This API will deallocate a protocomm instance that was created using protocomm_new().
