The void data type defines functions with no return value, functions with no argument list, and pointers to objects of an undefined type. It is used as follows:
void function-name (argument-list); return-type function-name (void); void *name;
Where
| function-name | is the name of the a function. |
| argument-list | is the arguments passed to the function. |
| return-type | is the return type of the function. |
| name | is the pointer to the void object(s). |
Refer to 2-Byte Scalars for information regarding the format of int types.
