INDEP - TXT_#?
 ----------------------------------------------------------------------------

   NAME

      txt_datdat() - Finds x byte data in y = x + z byte data
                     buffer.



   SYNOPSIS

      ptr = txt_datdat(dat1, len1, dat2, len2);

      UBYTE *txt_datdat(const UBYTE *, LONG,
                          const UBYTE *, LONG);



   FUNCTION

      This function allows to search for a binary data in
      greater or equal than that data binary buffer.



   INPUTS

      dat1 - Binary data in which search process will take 
             place.

      len1 - Size of that data.

      dat2 - Binary data that will be seek for in 'dat1'.

      len2 - Size of that data.



   RETURNS

      Important! Function returns pointer past the beginning of
      found 'dat2', so in other words you will have to 'ptr -=
      len2;' to achieve start of that found pattern.



   BASES

      None.



   NOTES

      There is also case insensitive variant of this function,
      called: 'txt_datidat()'. Please note that by def. there
      is no UTF-8 support in case insensitive version, but it
      may do support it when compiled to use 'utility.library'
      (-D___QDEV_UTILITYCHAREQ)! Plus both of these have ptr
      checking wrappers called: 
      'txt_pdatdat()' and 'txt_pdatidat()' respectively.



   SEE ALSO

      application.



   BUGS
