seekdir(3) OSS Library Calls Reference Manual
ERRORS
If any of the following conditions occurs, the seekdir( ) function sets errno to the corresponding
value:
[EBADF] The dir_pointer parameter does not refer to an open directory stream. This error
is returned instead of [EFAULT] if the process has copied and altered the struc-
ture pointed to by the dir_pointer parameter after the system has freed the buffer
that contains the structure.
[EFAULT] The dir_pointer parameter does not point to a valid directory structure open for
reading.
[EINVAL] Table overflow occurred after the last valid telldir( ) function call for a Guardian
disk volume or subvolume. Only the last 128 values returned by the telldir( )
function can be saved in the table.
RELATED INFORMATION
Functions: closedir(3), mkdir(2), opendir(3), readdir(3), rewinddir(3), rmdir(2), telldir(3).
STANDARDS CONFORMANCE
The POSIX standards leave some features to the implementing vendor to define. The following
features are affected in the HP implementation:
• The ramifications of buffering more than one directory entry per read operation are
defined.
• After a call to one of the exec set of functions, all open directory streams are closed
automatically.
• The ramifications of having both the parent and child processes access the same OSS
directory after a call to the fork( ) or tdm_fork( ) function are undefined.
• The consequences of calling directory functions with a dir_pointer parameter that does
not refer to a currently opened directory stream are defined. (The error value [EBADF]
or [EFAULT] is returned or a SIGSEGV or SIGILL signal is returned.)
• The error value [EBADF], [EFAULT], or [EINVAL] can be returned by the seekdir( )
function.
The following are HP extensions to the XPG4 Version 2 specification:
• The error values [EBADF], [EFAULT], and [EINVAL] can be returned.
