SECURE_PATH(3)						   BSD Library Functions Manual 					    SECURE_PATH(3)

NAME

     secure_path -- determine if a file appears to be ``secure''

LIBRARY

     System Utilities Library (libutil, -lutil)

SYNOPSIS

     #include <util.h>

     int
     secure_path(const char *path);

DESCRIPTION

     The secure_path() function takes a path name and returns zero if the referenced file is ``secure'', non-zero if not.  Any ``insecurity'',
     other than failure to access the referenced file, will be logged to the system log.

     To be ``secure'', the referenced file must exist, be a regular file (and not a directory), owned by the super-user, and writable only by the
     super-user.

SEE ALSO

     openlog(3)

HISTORY

     The secure_path() function is based on the BSD/OS implementation of same, and appeared in NetBSD 1.5 by kind permission.

OPENDISK(3)						   BSD Library Functions Manual 					       OPENDISK(3)

NAME

     opendisk -- open a disk partition

LIBRARY

     System Utilities Library (libutil, -lutil)

SYNOPSIS

     #include <util.h>

     int
     opendisk(const char *path, int flags, char *buf, size_t buflen, int iscooked);

DESCRIPTION

     opendisk() opens path, for reading and/or writing as specified by the argument flags using open(2), and the file descriptor is returned to
     the caller.  buf is used to store the resultant filename.	buflen is the size, in bytes, of the array referenced by buf (usually MAXPATHLEN
     bytes).  iscooked controls which paths in /dev are tried.

     opendisk() attempts to open the following variations of path, in order:

     path	  The pathname as given.

     pathX	  path with a suffix of 'X', where 'X' represents the raw partition of the device, as determined by getrawpartition(3), usually
		  ``c''.

     If path does not contain a slash (``/''), the following variations are attempted:

	   -   If iscooked is zero:

	       /dev/rpath   path with a prefix of ``/dev/r''.

	       /dev/rpathX  path with a prefix of ``/dev/r'' and a suffix of 'X' (q.v.).

	   -   If iscooked is non-zero:

	       /dev/path    path with a prefix of ``/dev/''.

	       /dev/pathX   path with a prefix of ``/dev/'' and a suffix of 'X' (q.v.).

RETURN VALUES

     An open file descriptor, or -1 if the open(2) failed.

ERRORS

     opendisk() may set errno to one of the following values:

     [EINVAL]		O_CREAT was set in flags, or getrawpartition(3) didn't return a valid partition.

     [EFAULT]		buf was the NULL pointer.

     The opendisk() function may also set errno to any value specified by the open(2) function.

SEE ALSO

     open(2), getrawpartition(3)

HISTORY

     The opendisk() function first appeared in NetBSD 1.3.
