- * This API provides functionality to use file descriptors to send logging
- * data to ASL.
- *
- * asl is retained by ASL and must still be closed by the caller by calling
- * asl_close() if the caller loses reference to it.  msg is copied by ASL and
- * similarly must still be freed by the caller by calling asl_free() if the
- * caller loses reference to it.  Any changes made to it after calling
- * asl_log_descriptor() are not applicable to the message used. descriptor
- * is treated differentlty based on the value of fd_type.
- *
- * If fd_type is ASL_LOG_DESCRIPTOR_READ, the descriptor must be open for read
- * access.  ASL uses GCD to read from the descriptor as data becomes available.
- * These data are line buffered and passed to asl_log.  When EOF is read, the
- * descriptor is closed.
- *
- * Example:
- * asl_log_descriptor(c, m, ASL_LEVEL_NOTICE, STDIN_FILENO, ASL_LOG_DESCRIPTOR_READ);
- *
- * If fd_type is ASL_LOG_DESCRIPTOR_WRITE, the descriptor is closed and a new
- * writable descriptor is created with the same fileno.  Any data written to
- * this new descriptor are line buffered and passed to asl_log.  When EOF is
- * sent, no further data are read.  The caller is responsible for closing the
- * new descriptor.  One common use for this API is to redirect writes to stdout
- * or stderr to ASL by passing STDOUT_FILENO or STDERR_FILENO as descriptor.
- *
- * Example:
- * asl_log_descriptor(c, m, ASL_LEVEL_NOTICE, STDOUT_FILENO, ASL_LOG_DESCRIPTOR_WRITE);
- * asl_log_descriptor(c, m, ASL_LEVEL_ERR, STDERR_FILENO, ASL_LOG_DESCRIPTOR_WRITE);
- *
- * @param asl
- *    (input) An ASL client handle
- * @param msg
- *    (input) An aslmsg (default attributes will be supplied if msg is NULL)
- * @param level
- *    (input) Log level (ASL_LEVEL_DEBUG to ASL_LEVEL_EMERG)
- * @param descriptor
- *    (input) An open file descriptor to read from
- * @param fd_type
- *    (input) Either ASL_LOG_DESCRIPTOR_READ or ASL_LOG_DESCRIPTOR_WRITE
- * @result Returns 0 for success, non-zero for failure
