open64(2) OSS System Calls Reference Manual
• The named file is a Guardian directory (/G or a directory in the /G file
system).
[ELOOP] Too many symbolic links were encountered in translating the path parameter.
[EMFILE] The system limit for open file descriptors per process has reached the maximum
permitted.
[ENAMETOOLONG]
One of these names is too long:
• The pathname pointed to by the path parameter
• A component of the pathname pointed to by the path parameter
• The intermediate result of pathname resolution when a symbolic link is
part of the path parameter
You can call the pathconf() function to obtain the applicable limits.
[ENETDOWN]
The call was blocked during access to a FIFO, and communication has been lost
with the remote node containing the other end of the FIFO.
[ENFILE] One of these conditions exists:
• The maximum number of file descriptors of this file type (socket, pipe,
etc.) for this processor are already open.
• The limit for open file descriptors of this file type has not been exceeded,
but the maximum number of all file descriptors for this processor are
already open.
[ENOENT] One of these conditions exists:
• The O_CREAT flag is not set, and the named file does not exist.
• O_CREAT is set, and the pathname prefix does not exist.
• The path parameter points to an empty string.
• The function call attempted to open a file in the Guardian file system, but
the specified pathname cannot be mapped to a valid Guardian filename.
• The path parameter points to a file on a remote HP NonStop node, but
communication with the remote node has been lost.
[ENOMEM] There was insufficient memory available to complete the operation.
[ENOROOT] One of these conditions exists:
• The root fileset of the local node (fileset 0) is not in the STARTED state.
• The current root fileset for the specified file is unavailable. The OSS
name server for the fileset might have failed.
• The specified file is on a remote HP NonStop node, and communication
with the remote name server has been lost.
