- * Open a file with authorization, updating the contents of the structures
- * pointed to by ndp, fmodep, and vap as necessary to perform the requested
- * operation. This function is used for both opens of existing files, and
- * creation of new files.
- *
- * Parameters: ndp The nami data pointer describing the
- * file
- * fmodep A pointer to an int containg the mode
- * information to be used for the open
- * vap A pointer to the vnode attribute
- * descriptor to be used for the open
- *
- * Indirect: * Contents of the data structures pointed
- * to by the parameters are modified as
- * necessary to the requested operation.
- *
- * Returns: 0 Success
- * !0 errno value
- *
- * Notes: The kauth_filesec_t in 'vap', if any, is in host byte order.
- *
- * The contents of '*ndp' will be modified, based on the other
- * arguments to this function, and to return file and directory
- * data necessary to satisfy the requested operation.
- *
- * If the file does not exist and we are creating it, then the
- * O_TRUNC flag will be cleared in '*fmodep' to indicate to the
- * caller that the file was not truncated.
- *
- * If the file exists and the O_EXCL flag was not specified, then
- * the O_CREAT flag will be cleared in '*fmodep' to indicate to
- * the caller that the existing file was merely opened rather
- * than created.
- *
- * The contents of '*vap' will be modified as necessary to
- * complete the operation, including setting of supported
- * attribute, clearing of fields containing unsupported attributes
- * in the request, if the request proceeds without them, etc..
- *
- * XXX: This function is too complicated in actings on its arguments
- *
- * XXX: We should enummerate the possible errno values here, and where
- * in the code they originated.
