int pcre2_set_compile_extra_options(pcre2_compile_context *ccontext,
  uint32_t extra_options);


This function sets additional option bits for pcre2_compile() that are housed in a compile context. It completely replaces all the bits. The extra options are:

 PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES  Allow x{df800} to x{dfff}
                                        in UTF-8 and UTF-32 modes
 PCRE2_EXTRA_ALT_BSUX                 Extended alternate u, U, and x
 PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL    Treat all invalid escapes as
                                        a literal following character
 PCRE2_EXTRA_ESCAPED_CR_IS_LF         Interpret 

 PCRE2_EXTRA_MATCH_LINE               Pattern matches whole lines
 PCRE2_EXTRA_MATCH_WORD               Pattern matches words
