NETREAD(3)						     Common Library Functions							NETREAD(3)

NAME

       netread - receive a message from a socket

SYNOPSIS

       #include "net.h"

       int netread (int s, char *buf, int nbytes);

       ssize_t netread_timeout (int s, void *buf, size_t nbytes, int timeout);

DESCRIPTION

       netread	receives  a  message  from  a  socket.	It overcomes the message fragmentation problem and always waits for all requested bytes to
       arrive or a timeout/error occurs.

RETURN VALUE

       This routine returns the number of bytes if the operation was successful, 0 if the connection was closed by the remote end  or  -1  if  the
       operation failed. In the latter case, serrno is set appropriately.

ERRORS

       EINTR	   The function was interrupted by a signal.

       EBADF	   s is not a valid descriptor.

       EAGAIN	   The socket is non-blocking and there is no message available.

       EFAULT	   buf is not a valid pointer.

       EINVAL	   nbytes is negative or zero.

       ENOTSOCK    s is not a socket.

       SECONNDROP  Connection closed by remote end.

       SETIMEDOUT  Timed out.

RFIO_FSEEK(3)						      Rfio Library Functions						     RFIO_FSEEK(3)

NAME

       rfio_fseek - positions/repositions a file

SYNOPSIS

       #include <sys/types.h>
       #include "rfio_api.h"

       int rfio_fseek (FILE *fp, long offset, int whence);

       Under Linux, for large files:
       #define _LARGEFILE64_SOURCE
       #include <sys/types.h>
       #include "rfio_api.h"

       int rfio_fseeko64 (FILE *fp, off64_t offset, int whence);

       For large files, under other systems:
       #include <sys/types.h>
       #include "rfio_api.h"

       int rfio_fseeko64 (FILE *fp, off64_t offset, int whence);

DESCRIPTION

       rfio_fseek positions/repositions to offset the file associated with the descriptor fp generated by a previous rfio_fopen.  whence indicates
       how to interpret the offset value:

	      SEEK_SET	   The offset is set from beginning of file.

	      SEEK_CUR	   The offset is added to current position.

	      SEEK_END	   The offset is added to current file size.
       rfio_fseeko64 can be used with large files and allows to use a 64 bit offset rather than a long.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       EBADF	    fp is not a valid descriptor.

       EINVAL	    incorrect value for whence.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SETIMEDOUT   Timed out.

       SEBADVERSION Version ID mismatch.

       SEINTERNAL   Internal error.

       SECONNDROP   Connection closed by remote end.

       SECOMERR     Communication error.
