posix_fadvise64

posix_fadvise(2)						System Calls Manual						  posix_fadvise(2)

NAME

       posix_fadvise(), posix_fadvise64() - file advisory information

SYNOPSIS


   Parameters
       fd	 The open file descriptor to which the fadvise operation applies.

       offset	 The begining of the specified range as a positive, byte offset.

       len	 The length of the specified range in bytes.

       advice	 Specifies advice to be applied to range.

DESCRIPTION

       The  function  is  used to advise the system about the expected behavior of the application with respect to the data in the file associated
       with the open file descriptor, fd, starting at offset and continuing for len bytes.  The specified range need not currently  exist  in  the
       file.  If len is zero, all data following offset is specified.

       It  should  be  noted that the effect of all hints is cumulative for a given file object.  All hints will be removed on processing the last
       close of the file object.

       The function may be used for large file access by a 32-bit application built with set to 64.

       The advice parameter is used to convey the hint to be applied to the data and may be one of the following values:

       Specifies that the application has no advice to give on its behavior with respect to the specified data.  It is the default  characteristic
       if no advice is given for an open file.

       Specifies that the application expects to access the specified range of data
	      sequentially from the lower offsets to higher offsets.

       Specifies that the application will expect to access the specified
	      specified range of data in a random order.

       Specifies that the application will expect to access the specified
	      range of data in the near future.

       Specifies that the application will expect that it will not
	      access the specified range of data in the near future.

       Specifies that the application will expect to access the specified range
	      of data once and then not reuse it thereafter.

       These values will be defined in

RETURN VALUE

	      Successful completion.
	      Failure.
		     is set to indicate the error.

ERRORS

       If the service fails, is set to one of the following values:

       The	      fd argument is not a valid file descriptor.

       The	      fd argument is associated with a pipe or FIFO.

       The posix_fadvise operation is not supported by the underlying file system.

       The value of   advice or one of the other input values has been found to be invalid.

       A designated hint is not supported by the underlying file object.
