Hiding a standard library function in c++
Thursday, April 25, 2013 c , c++ 0 Comments

I have a function abs in one of the libraries and I wanted to use that function by linking to that library.But I am facing this error below:

function abs used is #define abs(x) (x &gt; 0) ? x : -(x).

This is obviously from the standard includes that I used. So I found a some very nice ways to overcome this problem :

Wrapping the function name abs in parenthesis has resolved the problem right away.
```
(abs)(arguments)
```

Using the preprocessor directives Before you call the function abc in the library.
```
#undef abs
```
