Error in APR manual

[Damir Dezeljin]

Hi.

I noticed that the description of 'in' and 'out' pipes for
apr_file_pipe_create() is wrong.

I check the manual for creating / using pipes. The pipe_create cutout:
----
apr_status_t apr_file_pipe_create(
  apr_file_t **    in,
  apr_file_t **    out,
  apr_pool_t *    cont
)

Create an anonymous pipe.

Parameters:
in  The file descriptor to use as input to the pipe.
out  The file descriptor to use as output from the pipe.
cont  The pool to operate on.
----

Then I made a simple program:
----
...
#define IN
#define OUT
...
int main(void) {
    apr_file_t          *pipe[2];
    char                buf[]="0123456789";
    int                 len=10;
    ...
    rv = apr_file_pipe_create(
            &pipe[IN],
            &pipe[OUT],
            pool);
    ...
    rv = apr_file_write(pipe[IN], buf, &len);
    // This produce an error
    ...
}
----

So I try to use the other part of the pipe in apr_file_write (pipe[OUT])
and now the program works fine.
Am I doing something wrong or is realy a 'bug' in the manual?
