NAME
     DtDtsBufferToDataType - get the data type for a byte stream

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

DESCRIPTION
     The DtDtsBufferToDataType() function returns the  data  type
     name for a given byte stream.

     The buffer argument is a pointer to the buffer of  the  data
     to be typed.

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

     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   DtDtsBufferToDataType()
     function  returns  a  pointer to a data type name string, or
     NULL if no value could be determined.

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

     The DtDtsBufferToDataType() 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
     DtDts(5), DtDtsDataToDataType(3), DtDtsLoadDataTypes(3),
     DtDtsFreeDataType(3).
