Open System Services System Calls Reference Manual (G06.28+, H06.05+)

spt_fcntlx(2) OSS System Calls Reference Manual
• The request parameter is F_SETFL, and any file status flag other than
O_NONBLOCK, O_APPEND, O_CREAT, O_EXCL, O_SYNC,or
O_TRUNC is set. (Values set in the O_ACCMODE mask are ignored.)
• The request parameter is F_SETOWN, and the filedes parameter does
not specify a socket.
• The call attempted to set an advisory record lock on a file that is not a
regular file.
[EIO] An input or output error occurred. The device holding the file might be in the
down state, or both processors that provide access to the device might have
failed.
[EISGUARDIAN]
The value used for the filedes parameter is appropriate only in the Guardian
environment.
[EMFILE] The request parameter is F_DUPFD and the maximum number of open file
descriptors permitted are currently open in the calling process, or no file descrip-
tors greater than or equal to argument1 are available.
[ENETDOWN]
The request parameter is F_SETLK, the filedes parameter specifies a file on a
remote node, and communication with the remote node has been lost.
[ENOLCK] The request parameter is F_SETLK or F_SETLKW, and satisfying the lock or
unlock request would cause the number of locked regions in the system to
exceed a system-imposed limit.
[ENOTOSS] The filedes parameter specifies a socket, and the calling process is running in the
Guardian environment. You cannnot use spt_fcntlx( ) function on an OSS socket
from the Guardian environment.
[EWRONGID] One of these conditions occurred:
• The process attempted an operation through an operating system
input/output process (such as a terminal server process) that has failed or
is in the down state.
• The processor for the disk process of the specified file failed during an
input or output operation, and the backup process took over.
• The open file descriptor has migrated to a new processor, but the new
processor lacks a resource or system process needed for using the file
descriptor.
The file descriptor specified by the filedes parameter can only be closed.
For all other error conditions, errno is set to the appropriate Guardian file-system error number.
For more information about a specific Guardian file-system error, see the Guardian Procedure
Errors and Messages Manual.
