Why?
Normally, system provided shared API definitions are in /usr/include, and are referenced by "#include <name>" lines. If you are including an application API then you use '#include "name"' lines. Note the <> for system defined ones and "" for local application ones.
In addition, there is the -I option that tells the compiler where to look for includes that are not in the system provided ones.
