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 DtDtsFreeDataType3 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.
