pollsys then waits until the file can be read. The only possible cause is described above. This is POSIX compliant semantics for the read call. pollsys is a Solaris-ism (a system call entry point) for poll() and select(), I believe. Don Cragun would know definitely.

readdir
readdir(3UCB) SunOS/BSD Compatibility Library Functions readdir(3UCB)NAME
readdir - read a directory entry
SYNOPSIS
/usr/ucb/cc [ flag ... ] file ...
#include <sys/types.h>
#include <sys/dir.h>
struct direct *readdir(dirp)
DIR *dirp;
DESCRIPTION
The readdir() function returns a pointer to a structure representing the directory entry at the current position in the directory stream to
which dirp refers, and positions the directory stream at the next entry, except on read-only file systems. It returns a NULL pointer upon
reaching the end of the directory stream, or upon detecting an invalid location in the directory. The readdir() function shall not return
directory entries containing empty names. It is unspecified whether entries are returned for dot (.) or dot-dot (..). The pointer
returned by readdir() points to data that may be overwritten by another call to readdir() on the same directory stream. This data shall not
be overwritten by another call to readdir() on a different directory stream. The readdir() function may buffer several directory entries
per actual read operation. The readdir() function marks for update the st_atime field of the directory each time the directory is actu-
ally read.
RETURN VALUES
The readdir() function returns NULL on failure and sets errno to indicate the error.
ERRORS
The readdir() function will fail if one or more of the following are true:
EAGAIN Mandatory file/record locking was set, O_NDELAY or O_NONBLOCK was set, and there was a blocking record lock.
EAGAIN Total amount of system memory available when reading using raw I/O is temporarily insufficient.
EAGAIN No data is waiting to be read on a file associated with a tty device and O_NONBLOCK was set.
EAGAIN No message is waiting to be read on a stream and O_NDELAY or O_NONBLOCK was set.
EBADF The file descriptor determined by the DIR stream is no longer valid. This results if the DIR stream has been closed.
EBADMSG Message waiting to be read on a stream is not a data message.
EDEADLK The read() was going to go to sleep and cause a deadlock to occur.
EFAULT buf points to an illegal address.
EINTR A signal was caught during the read() or readv() function.
EINVAL Attempted to read from a stream linked to a multiplexor.
EIO A physical I/O error has occurred, or the process is in a background process group and is attempting to read from its control-
ling terminal, and either the process is ignoring or blocking the SIGTTIN signal or the process group of the process is
orphaned.
ENOENT The current file pointer for the directory is not located at a valid entry.
ENOLCK The system record lock table was full, so the read() or readv() could not go to sleep until the blocking record lock was
removed.
ENOLINK fildes is on a remote machine and the link to that machine is no longer active.
ENXIO The device associated with fildes is a block special or character special file and the value of the file pointer is out of
range.
EOVERFLOW The value of the direct structure member d_ino cannot be represented in an ino_t.
USAGE
The readdir() function has a transitional interface for 64-bit file offsets. See lf64(5).
SEE ALSO cc(1B), getdents(2), readdir(3C), scandir(3UCB), lf64(5)NOTES
Use of these interfaces should be restricted to only applications written on BSD platforms. Use of these interfaces with any of the sys-
tem libraries or in multi-thread applications is unsupported.
