| ## Name
 | |
| 
 | |
| basename - extract file name from a path
 | |
| 
 | |
| ## Synopsis
 | |
| 
 | |
| ```**c++
 | |
| #include <libgen.h>
 | |
| 
 | |
| char* basename(char* path);
 | |
| ```
 | |
| 
 | |
| ## Description
 | |
| 
 | |
| Given a file path, `basename()` returns that file's name. `basename()` works
 | |
| purely lexically, meaning it only manipulates the path as a string, and does
 | |
| not check if such a file actually exists.
 | |
| 
 | |
| A call to `basename()` may reuse and modify the passed in `path` buffer. Do not
 | |
| expect it to have the same value after calling `basename()`.
 | |
| 
 | |
| ## Return value
 | |
| 
 | |
| `basename()` returns the file name as a string. This string may be allocated
 | |
| in static memory, or it may point to some part of the original `path` buffer.
 | |
| Do not `free()` the returned string, and do not `free()` the original `path`
 | |
| buffer while using the returned string.
 | |
| 
 | |
| ## Examples
 | |
| 
 | |
| ```c++
 | |
| #include <AK/LogStream.h>
 | |
| #include <libgen.h>
 | |
| 
 | |
| int main()
 | |
| {
 | |
|     char path1[] = "/home/anon/ReadMe.md";
 | |
|     dbg() << basename(path1); // should be "ReadMe.md"
 | |
| 
 | |
|     char path2[] = "foo/bar/";
 | |
|     dbg() << basename(path2); // should be "bar"
 | |
| 
 | |
|     char path3[] = "foo";
 | |
|     dbg() << basename(path3); // should be "foo"
 | |
| 
 | |
|     char path4[] = "/";
 | |
|     dbg() << basename(path4); // should be "/"
 | |
| }
 | |
| ```
