i just want to know if it is possible to view the header files like stdio,stdlib,string etc.i want to see the prototype declarations inside it.
Thanks

Your compiler should have an include folder somewhere that has all the header files in it.

Those don't have the actual code in them tho (the code was compiled into library objects already). You probably don't have the C source installed by default (the source for your compiler may not be open either! if it is available, you probably have to download it).

edit: sorry, the OP just asked for the prototypes; those are in the headers.

GNU C Library - GNU Project - Free Software Foundation (FSF)

To see an implementation of the standard library.

If all you want is the prototype declarations though, your system has them somewhere. Check what directories your compiler is including and search there.

See if you can compile your program with the "-P" option (iff the compiler supports it).
Afterwards view the resultant .i file that the preprocessor generates.

i'm using visual studio 2005.where can i see in it,i mean which directory.

**Bladactania** · 04-24-2009

Look in the Installation Directory. For me it's c:\program files\MS Visual Studio 8\VC\include

Thanks for all the help.i've seen the include folder.

If you're using Visual Studio, then all you need to do is right click on the header name in your source file and select the first option "Open Document <whatever>" where <whatever> is the name of the header file you wish to open.

Thanks hk_mp5kpdw. That was cool. also i've a question regarding visual studio.how can i use its help efficiently. suppose that i want to know about any standard library function( like malloc,swab etc) how can i get it. in turbo c++ pressing CNTRL+F1(after placing the cursor undre the function) gives the information regarding the function, is there any such shortcut in visual studio.any help would be appreciated.

In most cases, you can just click on the function name in your source file (doesn't need to be highlighted or anything like that, just so the cursor has been clicked somewhere within the name) and press F1.
