Here is my understanding. A .h file is, as you said, a header file. As
such, it contains the headers of the .c (or .cpp) file with which it
is associated. For instance, if you make a dll with two functions, add
and subtract, you make the .c/.cpp file in which you define and code
the functions:
int add(int a, int b){
return(a+b);
}
int subtract(int a, int b){
return(a-b);
}
Now, in the .h file, you only define the headers:
int add(int a, int b);
int subtract(int a, int b);
Then, when you make the dll file, you can distribute the .h file along
with the dll. This lets those who use your dll get a look at exactly
what the functions are called, what they expect, and what variable
type they return, either as a substitute for, or in addition to,
documentation. Hope this makes sense.
