CRTL, fdopen, Description

 *Conan The Librarian

    The fdopen function allows you to access a file, originally
    opened by one of the UNIX I/O functions, with Standard I/O
    functions. Ordinarily, a file can be accessed by either a file
    descriptor or by a file pointer, but not both, depending on the
    way you open it.
