Answer / vignesh1988i

it's simple.....

just have ur function definition in one Cpp or C file.....ie save it as .cpp or .C file....
then include the file as #include "program.c"
and then wherever you need call that functionin an another program...
for example:
let me add my own ADDITION function in my library.....

this is my first file stored in .C....
int add(int a,int b)
{
int c;
c=a+b;
return c;
}
the file name for the above is add.c

then am opening my main program file in .c mode ....
#include<stdio.h>
#include<conio.h>
#include"add.c"
void main()
{
int a,b,c;
scanf("%d%d",&a,&b);
c=add(a,b);
printf("\n the added sum is :%d",c);
getch();
}



thank u

Using ar utility.
Let's say we have lib1.c lib2.c and myprog.c
We want to do a library from lib1.c && lib2.c, and compile
myprog.c with this library afterwards.
The steps are:
Compile
1. gcc -c lib1.c -o lib1.o
2. gcc -c lib2.c -o lib2.o

Create archive named libmy.a
3. ar -rcsv libmy.a lib1.o lib2.o

Compile myprog with newly created lib
4. gcc myprog.c -L. -lmy -o myprog

Do you mean funtion(s) in libc? if not, it is very simple.
Irrespective or static or dynamic, the library always
contains an executable code but not linked. When application
uses the library, the code is linked at application link
time or load time depending on whether the library is static
or dynamic respectively.

for adding function in a library, just add the new function
as if you are adding any other function and recompile it as
a library. When linked with application, the new function
will become useable.

Answer / vivek

By library its generally meant an executable library. In
which case one can write a wrapper for the existinig DLL.
This will ofcourse require one to know the function
prototype of all exported functions.

If its a static library then simple write another lib and
add the existing one of the libs to link against.

write a program to swap bits in a character and return the value prototype of function char fun (char a, charb flag c) where fun returns a char, char a is a the value char b is the bit to be changed and flag c is the bit value for eg: x=fun(45,7,0) since 45 is 0010 0101 and ow x should contain the value 65 (0110 0101)
