SunOS release 5.7, ABI, SVID, and SVR4 versions support only the -O_APPEND, -O_SYNC, -O_NDELAY, and -O_NONBLOCK flags. Thus, -O_SYNC should be used in place of -FSYNC, and -O_NONBLOCK should be used in place of -FNDELAY and -FNBIO. -O_NONBLOCK should also be used in place of -O_NDELAY, which is being phased out.

mount() (2)

C# 

The SunOS release 4 version of mount() and the SunOS release 5.7, or the ABI, SVID, or SVR4 version of mount() are incompatible in a number of respects. The first argument in the SunOS release 4 version, type, is the file system type name, while in SunOS release 5.7, ABI, SVID, and SVR4 versions, the first argument, fs, is the name of the file system. In SunOS release 5.7, ABI, SVID, and SVR4 versions, the file system type name, fstype, is the fourth argument to mount(). The SunOS release 4 version uses a single parameter (caddr_t data, the fourth argument) to pass type-specific arguments, while the SunOS release 5.7, ABI, SVID, and SVR4 version uses two parameters (five and six: const char *dataptr and int datalen). Also, SunOS release 5.7, ABI, SVID, and SVR4 versions include <sys/types.h> before <sys/mount.h> while the SunOS release 4 version does not. The SunOS release 4 version of <sys/mount.h> defines symbolic constants for the mount() flags argument (M_NEWTYPE, M_RDONLY, M_NOSUID, M_NEWTYPE, M_GRPID, M_REMOUNT , M_NOSUB, M_MULTI) that are not defined in SunOS release 5.7, or the ABI, SVID, or SVR4 <sys/mount.h>. Instead, replace M_RDONLY with MS_RDONLY, M_NOSUID with MS_NOSUID, and M_REMOUNT with MS_REMOUNT. The M_NEWTYPE flag is specific to the SunOS release 4 version of mount() and no replacement is required for SunOS release 5.7, ABI, SVID, or SVR4 versions. The functionality of the following flags, defined in <sys/mount.h>, is not supported by the SunOS release 5.7, or the ABI, SVID, or SVR4 versions: M_NOSUB, M_GRPID, M_MULTI. SunOS release 4 mount() uses the following errno values, which are not returned by the SunOS release 5.7, or the ABI, SVID, or SVR4 version: ENODEV, EACCES, EMFILE, ENOMEM.

The mode argument to open() is of type int in the SunOS release 4 software and of type mode_t in SunOS release 5.7, ABI, SVID, and SVR4 versions. In the SunOS release 4 software, if the path argument is an empty string, the kernel maps this empty pathname to `.', the current directory. In SunOS release 5.7, ABI, SVID, and SVR4 versions, if path points to an empty string an error results. In the SunOS release 4 software, if the O_NDELAY or O_NONBLOCK flag is set on a call to open, only the open() call itself is effected. In SunOS release 5.7, ABI, SVID, and SVR4 versions, if the O_NDELAY or O_NONBLOCK flag is set on a call to open(), the corresponding flag is set for that file descriptor and subsequent reads and writes to that descriptor will not block.

Also, SunOS release 5.7, ABI, SVID, and SVR4 versions include <sys/types.h> and <sys/stat.h> while the SunOS release 4 version does not.

The pid argument to ptrace() is of type int in the SunOS release 4 software and of type pid_t in theSunOS release 5.7 version. Also, the SunOS release 5.7 version includes <sys/types.h> while the SunOS release 4 version includes <signal.h>, <sys/ptrace.h>, and <sys/wait.h>.

The following errno flag is valid for the SunOS release 4 version of this system call, but is not valid in the SunOS release 5.7 version: EPERM.

The SunOS release 5.7 version of setpgrp() does not accept an argument, and setpgrp() also creates a new session. However, if pgrp is zero and pid refers to the calling process, then SunOS release 4 setpgrp() call is identical to a SunOS release 5.7 setpgrp() call with no arguments. Also, SunOS release 4 setpgrp() returns a value of type int, while SunOS release 5.7, setpgrp() returns a value of type pid_t. The SunOS release 5.7 version includes <unistd.h> and <sys/types.h> while the SunOS release 4 version does not.

In SunOS release 4, wait() is automatically restarted when a process receives a signal while awaiting termination, unless the SV_INTERRUPT bit is set in the flags for that signal.

write() (2V)

C# 

In the SunOS release 4 software, if the object that the descriptor refers to is marked for non-blocking I/O, using the FIONBIO request to ioctl(), or using fcntl() to set the FNDELAY or O_NDELAY flag, write() returns -1 and sets errno to EWOULDBLOCK.

In the SunOS release 5.7 software, on a write() to a regular file, if O_NDELAY or O_NONBLOCK is set, write() returns -1 and sets errno to EAGAIN.

On write() requests to a pipe or FIFO with O_NONBLOCK or O_NDELAY set, write() does not block the process. If some data can be written without blocking the process, write() writes what it can and returns the number of bytes written; otherwise, when O_NONBLOCK is set, it returns -1 and sets errno to EAGAIN and when O_NDELAY is set, it returns 0.

With O_NDELAY set, write() requests for {PIPE_BUF} or fewer bytes either succeed completely and return nbytes, or return 0. A write() request for greater than {PIPE_BUF} bytes either transfers what it can and returns the number of bytes written, or transfers no data and returns 0. Also, if a request is greater than {PIPE_BUF} bytes and all data previously written to the pipe has been read, write() transfers at least {PIPE_BUF} bytes.

The SunOS release 5.7 write() routine does not support 4.2 BSD style non-blocking I/O.
