DtDtsBufferToDataType(3)

     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().
