-
-ANSI_SYNOPSIS
- #include <stdio.h>
- FILE *fdopen(int <[fd]>, const char *<[mode]>);
- FILE *_fdopen_r(void *<[reent]>,
- int <[fd]>, const char *<[mode]>);
-
-TRAD_SYNOPSIS
- #include <stdio.h>
- FILE *fdopen(<[fd]>, <[mode]>)
- int <[fd]>;
- char *<[mode]>;
-
- FILE *_fdopen_r(<[reent]>, <[fd]>, <[mode]>)
- char *<[reent]>;
- int <[fd]>;
- char *<[mode]>);
-
-DESCRIPTION
-<<fdopen>> produces a file descriptor of type <<FILE *>>, from a
-descriptor for an already-open file (returned, for example, by the
-system subroutine <<open>> rather than by <<fopen>>).
-The <[mode]> argument has the same meanings as in <<fopen>>.
-
-RETURNS
-File pointer or <<NULL>>, as for <<fopen>>.
-
-PORTABILITY
-<<fdopen>> is ANSI.
