How to compile or link a .c file included as a header?

Question

I am trying to make an SSL socket. I have done some research and I found this answer in stackoverflow too:

I created a C file and I include the same headers:

#include <openssl/applink.c>
#include <openssl/bio.h>
#include <openssl/ssl.h>
#include <openssl/err.h>

But when I try to compile it, it makes this error:

socketMng.c:12:10: fatal error: openssl/applink.c: No such file or directory
 #include <openssl/applink.c>

I can't find that file in /usr/include/openssl/. I find that file in a folder named mn... I also included using quotation marks instead of <> from that folder but does not work.

Can .c included form the header? (I have never seen it) How can I solve it?

I already have libssl-dev installed.

Thanks

including C file into another file is legal, but not advisable thing to do. Why do you want to do so ? You need to compile them together instead of including it — Gabson, May 16 '18 at 10:51
You would only need it on windows if you load openssl dll, if you are not on windows you can remove that include — Pras, May 16 '18 at 11:09

Can .c file be included from the header?

Yes. All that include does is to take a file and paste its content instead of the include statement. Depending on who you ask it could be bad design, but it is perfectly valid.
