Hi all,
I'm writing to this mail list because I have a problem with apr and I
don't know if it is a bug or an error of mine.
I have installed apr-0.9.4 on my system (RedHat linux 9.0 with
glibc-2.3.2-27.9.7).
I toke client.c inside test directory and I have modified it (only a few
lines) to query a particular system.
The problem is that the function apr_socket_recv doesn't read all the
output but only a part of it. This function returns APR_SUCCESS before
all the output is sent.
Shall I set a particular option?
The program is this.
#include <stdlib.h>
#include "apr_network_io.h"
#include "apr_errno.h"
#include "apr_general.h"
#include <errno.h>
#define STRLEN 40000
#define GET_CMD "GET %s HTTP/1.0\r\n\r\n"

Can someone help me?
Where is my error?
Thanks for the support
