module PCRE2

The following option bits can be passed only to pcre2_compile(). However, they may affect compilation, JIT compilation, and/or interpretive execution. The following tags indicate which: C alters what is compiled by pcre2_compile() J alters what is compiled by pcre2_jit_compile() M is inspected during pcre2_match() execution D is inspected during pcre2_dfa_match() execution

The following option bits can be passed to pcre2_compile(), pcre2_match(), or pcre2_dfa_match(). PCRE2_NO_UTF_CHECK affects only the function to which it is passed. Put these bits at the most significant end of the options word so others can be added next to them

Request types for pcre2_config().

Options for pcre2_pattern_convert().

Miscellaneous error codes for pcre2_match(), substring extraction functions, context functions, and serializing functions. They are in numerical order. Originally they were in alphabetical order too, but now that PCRE2 is released, the numbers must not be changed.

Error codes for pcre2_compile(). Some of these are also used by pcre2_pattern_convert().

“Expected” matching error codes: no match and partial match.

Error codes for UTF-16 validity checks

Error codes for UTF-32 validity checks

Error codes for UTF-8 validity checks

Error 159 is obsolete and should now never occur

An additional compile options word is available in the compile context.

Request types for pcre2_pattern_info()

These are for pcre2_jit_compile().

Newline and R settings, for use in compile contexts. The newline values must be kept in step with values set in config.h and both sets must all be greater than zero.

These are for pcre2_match(), pcre2_dfa_match(), pcre2_jit_match(), and pcre2_substitute(). Some are allowed only for one of the functions, and in these cases it is noted below. Note that PCRE2_ANCHORED, PCRE2_ENDANCHORED and PCRE2_NO_UTF_CHECK can also be passed to these functions (though pcre2_jit_match() ignores the latter since it bypasses all sanity checks).
