     CREAT(S)		      XENIX System V		      CREAT(S)

     Name
	  creat - Creates a new file or rewrites an existing one.

     Syntax
	  int creat (path, mode)
	  char *path;
	  int mode;

     Description
	  creat creates a new ordinary file or prepares to rewrite an
	  existing file named by the pathname pointed to by path.

	  If the file exists, the length is truncated to 0 and the
	  mode and owner are unchanged.	 Otherwise, the file's owner
	  ID is set to the process' effective user ID, the file's
	  group ID is set to the process' effective group ID, and the
	  access permission bits (i.e., the low-order 12 bits of the
	  file mode) are set to the value of mode.  mode may have the
	  same values as described for chmod(S).  creat will then
	  modify the access permission bits as follows:

	       All bits set in the process' file mode creation mask
	       are cleared.  See umask(S).

	       The ``save text image after execution bit'' is cleared.
	       See chmod(S).

	  Upon successful completion, a non-negative integer, namely
	  the file descriptor, is returned and the file is open for
	  writing, even if the mode does not permit writing.  The file
	  pointer is set to the beginning of the file.	The file
	  descriptor is set to remain open across exec system calls.
	  See fcntl(S).	 No process may have more than 60 files open
	  simultaneously.  A new file may be created with a mode that
	  forbids writing.

	  creat will fail if one or more of the following are true:

	       A component of the path prefix is not a directory.
	       [ENOTDIR]

	       A component of the path prefix does not exist.
	       [ENOENT]

	       Search permission is denied on a component of the path
	       prefix.	[EACCES]

	       The pathname is null.  [ENOENT]

	       The file does not exist and the directory in which the
	       file is to be created does not permit writing.
	       [EACCES]

	       The named file resides or would reside on a read-only
	       file system.  [EROFS]

	       The file is a pure procedure (shared text) file that is
	       being executed.	[ETXTBSY]

	       The file exists and write permission is denied.
	       [EACCES]

	       The named file is an existing directory.	 [EISDIR]

	       Sixty file descriptors are currently open.  [EMFILE]

	       path points outside the process' allocated address
	       space.  [ENOSPC]

	       The directory to contain the file cannot be extended.
	       [EFAULT]

	       The system file table is full.  [ENFILE]

     Return Value
	  Upon successful completion, a nonnegative integer, namely
	  the file descriptor, is returned.  Otherwise, a value of -1
	  is returned and errno is set to indicate the error.

     See Also
	  close(S), dup(S), lseek(S), open(S), read(S), umask(S),
	  write(S)

     Notes
	  open(S) is preferred to creat.
