c - Given a header file, Is there a way I can find out which library it belongs to? -

the source codes downloaded internet has lot of non standard, uncommon header files different depended modules, say.

#include<calendar.h>

#include <vconf.h>

given header file, there way find out files these headers fetched from?

look @ documentation of lib header belongs may best way.

you may header , note down function names , search through lib define symbol belongs function

edit:
ah thought have bunch of libs , headers , not know have link functionality declared in specific header

in case looking @ documentation downloaded source code may way (mostly information in install or readme - file)
