System Functions (s and S) spt_writex(2)
• An attempt was made to write to a pipe that has only one end open.
• An attempt was made to write to a socket that is shut down or closed.
[ETIMEDOUT]
Data transmission on the socket timed out.
[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.

STANDARDS CONFORMANCE
This function is an extension to the UNIX 98 specification. Interfaces documented on this refer-
ence page conform to IEEE Std 1003.1c-1995, POSIX System Application Program Interface,
with these exceptions:
• The use of the header file spthread.h is an HP exception to the POSIX standard.
• When a signal arrives during a call to the spt_writex() function, instead of returning an
EINTR error to the application, the spt_writex() retries the I/O operation, except in this
case: If the fork() function is called by a signal handler that is running on a thread per-
forming an spt_writex() call, the spt_writex() call in the child process returns an
EINTR error to the application.
The POSIX standard allows certain behaviors of write() to be implementer-defined. For an indi-
cation of the HP implementation behaviors, see the write(2) reference page either online or in
the Open System Services System Calls Reference Manual.
