PCRE2_SET_NEWLINE(3) Library Functions ManualPCRE2_SET_NEWLINE(3)PCRE2 - Perl-compatible regular expressions (revised API)
#include <pcre2.h>int pcre2_set_max_varlookbehind(pcre2_compile_context *ccontext,uint32_tvalue);
This sets a maximum length for the number of characters matched by a variable-length lookbehind assertion. The default is set when PCRE2 is built, with the ultimate default being 255, the same as Perl. Lookbehind assertions without a bounding length are not supported. The result is always zero. There is a complete description of the PCRE2 native API in thepcre2apipage and a description of the POSIX API in thepcre2posix page.
