## Chapter 2. Cygwin Functions

These functions are specific to Cygwin itself, and probably won't be found anywhere else.

## cygwin_attach_handle_to_fd

`extern "C" int cygwin_attach_handle_to_fd(` | name, |
| fd, |
| handle, |
| bin, |
| access`)`; |

`char *name`;
`int fd`;
`HANDLE handle`;
`int bin`;
`int access`;

This function can be used to turn a Win32 "handle" into a posix-style file handle. `fd` may be -1 to make cygwin allocate a handle; the actual handle is returned in all cases.
