NAME
     DtDtsBufferToAttributeValue - get a  single  data  attribute
     value for a byte stream

SYNOPSIS
     #include <Dt/Dts.h>
     char *DtDtsBufferToAttributeValue(const void *buffer,
                                       const int size,
                                       const char *attr_name,
                                       const char *opt_name);

DESCRIPTION
     The DtDtsBufferToAttributeValue() function  returns  a  data
     attribute  value  for a given byte stream.  The buffer argu-
     ment is a pointer to the buffer of the data to be typed.

     The size argument is the size of the buffer in bytes.

     The attr_name argument is a name of the attribute.

     The opt_name argument can be used to specify a  name  to  be
     associated with the buffer.  If the opt_name argument is not
     NULL, it is used as a pseudo file name in typing; otherwise,
     certain  attributes  may  be  returned  as  NULL because the
     filename components could not be determined.

RETURN VALUE
     Upon  successful   completion,   the   DtDtsBufferToAttribu-
     teValue()  function  returns  a  pointer to a data attribute
     value string, or NULL if no value could be determined.

APPLICATION USAGE
     The application should  use  the  DtDtsFreeAttributeValue(3)
     function to release the memory for the returned value.

     The DtDtsBufferToAttributeValue() function assumes that  the
     buffer is readable and writable by the user, group and other
     file classes and selects a type accordingly.  An application
     requiring  a  type based on read-only permissions should use
     DtDtsDataToDataType().

SEE ALSO

     DtDtsFreeAttributeValue(3).
