+FUNCTION
+<<fdopen>>---turn open file into a stream
+
+INDEX
+	fdopen
+INDEX
+	_fdopen_r
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	FILE *fdopen(int <[fd]>, const char *<[mode]>);
+	FILE *_fdopen_r(struct _reent *<[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]>)
+	struct _reent *<[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.
