# Method Parser.RCS()->DeltatextIterator()->parse_deltatext_section()

Method parse_deltatext_section

  ``protected` `int` parse_deltatext_section(`array` `raw`, `int` `o`)`

Description

  Chops off the first deltatext section from the token array `raw` and returns the rest of the string, or the value `0` (zero) if we had already visited the final deltatext entry. The deltatext's data is stored destructively in the appropriate entry of the revisions array.

Note

  `raw`+`o` must start with a deltatext entry for this method to work

FIXME

  does not handle rcsfile(5) newphrase skipping

FIXME

  if the rcs file is truncated, this method writes a descriptive error to stderr and then returns 0 - some nicer error handling wouldn't hurt
