Open System Services System Calls Reference Manual (G06.29+, H06.08+, J06.03+)

System Functions (s and S) spt_readvz(2)
• The processor for the disk process of the specified file failed during an
input or output operation, and takeover by the backup process occurred.
• The open file descriptor has migrated to a new processor, but the new
processor lacks a resource or system process needed for use of 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.
See the Guardian Procedure Errors and Messages Manual for more information about a specific
Guardian file-system error.

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_readvz() function, instead of returning an
EINTR error to the application, the spt_readvz() 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_readvz() call, the spt_readvz() call in the child process returns an
EINTR error to the application.
HP extensions to the XPG4 Version 2 specification are:
• The errno values [ECONNRESET], [EFAULT], [EFILEBAD], [EINVAL], [EISDIR],
[EISGUARDIAN], [ENETDOWN], [ENOTCONN], [ETIMEDOUT], and [EWRON-
GID] can be returned.
