No. I haven't tried to compile it.
Which version of OrangeFS are you using?
Send me your PVFS configuration file.

Hello and thanks for replying,
i already did that
char *buffer = (char *) malloc( count * (sizeof(char) + 1)
but it didn't work too
Have you compiled it at all?
Does it work for you?
I'm sure i've made a mistake in the code, but i can't find it
and i have to find it as soon as possible cause i need it
May you please help me?
Thanks

Hello,
i'm trying to create a file and read from it.The creation is working fine. When
i'm trying to read the file, i get an error when i call the "pvfs_sys_read"
invalid (NULL) required argumentPVFS_isys_io call: Invalid
argumentPVFS_sys_read : Invalid argument (error class: 0)
The problem is in the following line:
" ret = PVFS_sys_read(resp_create.ref, file_req, 0,buffer, mem_req,
&credentials, &resp_io, hints);"I can't understand which one of the arguments
is causing the problem,can you understand?How can i solve it?
The program is as follows:
#include <stdio.h>#include <stdlib.h>#include <unistd.h>#include <limits.h>
#include <string.h>
#include <sys/time.h>#include <sys/types.h>#include <sys/stat.h>#include

if (ret == 0) { PVFS_Request_free(&mem_req);
} else { PVFS_perror("PVFS_sys_read === ", ret);
printf("ret = %d\n",ret); } PVFS_sys_finalize();
}
Can you understand where the problem is?Where is that NULL value that causes
the problem?
Thanks, in advance
