name_open()

Open a name for a server connection

Synopsis:

#include <sys/iofunc.h>
#include <sys/dispatch.h>

int name_open( const char * name, 
               int flags );

Since:

BlackBerry 10.0.0

Arguments:

name
The name that you want to open for a server connection.
flags
Flags that affect the function's behavior:
  • NAME_FLAG_ATTACH_GLOBAL — search for the name globally instead of locally.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The name_open() function opens name for a server connection. No ordering is guaranteed when accessing resources on other nodes.

Returns:

A nonnegative integer representing a side-channel connection ID (see ConnectAttach()), or -1 if an error occurred ( errno is set).

Errors:

EACCES
Search permission is denied on a component of the name.
EBADFSYS
While attempting to open the named file, either the file itself or a component of the path prefix was found to be corrupted. A system failure — from which no automatic recovery is possible — occurred while the file was being written to, or while the directory was being updated. You'll need to invoke appropriate systems-administration procedures to correct this situation before proceeding.
EBUSY
The connection specified by name has already been opened and additional connections aren't permitted.
EINTR
The name_open() operation was interrupted by a signal.
EISDIR
The named path is a directory.
ELOOP
Too many levels of symbolic links or prefixes.
EMFILE
Too many file descriptors are currently in use by this process.
ENAMETOOLONG
The length of the name string exceeds PATH_MAX, or a pathname component is longer than NAME_MAX.
ENFILE
Too many files are currently open in the system.
ENOENT
The connection specified by name doesn't exist.
ENOTDIR
A component of the name prefix isn't a directory.

Examples:

See name_attach().
