+FUNCTION
+<<remove>>---delete a file's name
+
+INDEX
+	remove
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	int remove(char *<[filename]>);
+
+	int _remove_r(void *<[reent]>, char *<[filename]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	int remove(<[filename]>)
+	char *<[filename]>;
+
+	int _remove_r(<[reent]>, <[filename]>)
+	char *<[reent]>;
+	char *<[filename]>;
+
+DESCRIPTION
+Use <<remove>> to dissolve the association between a particular
+filename (the string at <[filename]>) and the file it represents.
+After calling <<remove>> with a particular filename, you will no
+longer be able to open the file by that name.
+
+In this implementation, you may use <<remove>> on an open file without
+error; existing file descriptors for the file will continue to access
+the file's data until the program using them closes the file.
+
+The alternate function <<_remove_r>> is a reentrant version.  The
+extra argument <[reent]> is a pointer to a reentrancy structure.
+
+RETURNS
+<<remove>> returns <<0>> if it succeeds, <<-1>> if it fails.
+
+PORTABILITY
+ANSI C requires <<remove>>, but only specifies that the result on
+failure be nonzero.  The behavior of <<remove>> when you call it on an
+open file may vary among implementations.
+
+Supporting OS subroutine required: <<unlink>>.
