This might be known to many but I recently tried it and got it working.
Suppose you make a function in C(for example here we take a simple function which calculates the square of a number).
Its a fairly simple one and I want to add in in a library thus making its reuse possible.
(Please note I am taking a very simple scenario because the actual program is not the point of focus here, but the procedure is)
int square(int n)
Compile the file:
Compile the file in which you have written this function. Lets call it “sqr.c”. A new file called “sqr.obj” is created contained compiled code.
Add the function to Library:
Add the function to the library “maths.lib” using the following command.
C:\>tlib maths.lib + c:\sqr.obj
Please note the paths. Your paths may be different than mine!
here, maths.lib is the library and + is a switch which indicates that we want to add a new function to the library and the object file is at the given path.
Add the prototype of square() function in a header file (lets say “square.h”) This file should be included in the program where we want to use the function. we can use it as:
Thats all !
Use the function and enjoy !!
Hope it helps.
