The input parameters constrain which meaning(s) is/are valid\n * in the current context.\n *\n * Exactly one of <node_p> and <code_point_p> must be non-NULL.\n *\n * If <code_point_p> is not NULL, the context is expecting the result to be a\n * single code point. If this \\N instance turns out to a single code point,\n * the function returns TRUE and sets *code_point_p to that code point.\n *\n * If <node_p> is not NULL, the context is expecting the result to be one of\n * the things representable by a regnode. If this \\N instance turns out to be\n * one such, the function generates the regnode, returns TRUE and sets *node_p\n * to point to that regnode.\n *\n * If this instance of \\N isn't legal in any context, this function will\n * generate a fatal error and not return.\n *\n * On input, RExC_parse should point to the first char following the \\N at the\n * time of the call. On successful return, RExC_parse will have been updated\n * to point to just after the sequence identified by this routine. Also\n * *flagp has been updated as needed.\n *\n * When there is some problem with the current context and this \\N instance,\n * the function returns FALSE, without advancing RExC_parse, nor setting\n * *node_p, nor *code_point_p, nor *flagp.\n *\n * If <cp_count> is not NULL, the caller wants to know the length (in code\n * points) that this \\N sequence matches. This is set even if the function\n * returns FALSE, as detailed below.\n *\n * There are 5 possibilities here, as detailed in the next 5 paragraphs.\n *\n * Probably the most common case is for the \\N to specify a single code point.\n * *cp_count will be set to 1, and *code_point_p will be set to that code\n * point.\n *\n * Another possibility is for the input to be an empty \\N{}, which for\n * backwards compatibility we accept. *cp_count will be set to 0. *node_p\n * will be set to a generated NOTHING node.\n *\n * Still another possibility is for the \\N to mean [^\\n]. *cp_count will be\n * set to 0. *node_p will be set to a generated REG_ANY node.\n *\n * The fourth possibility is that \\N resolves to a sequence of more than one\n * code points. *cp_count will be set to the number of code points in the\n * sequence. *node_p * will be set to a generated node returned by this\n * function calling S_reg().\n *\n * The final possibility is that it is premature to be calling this function;\n * that pass1 needs to be restarted. This can happen when this changes from\n * /d to /u rules, or when the pattern needs to be upgraded to UTF-8. The\n * latter occurs only when the fourth possibility would otherwise be in\n * effect, and is because one of those code points requires the pattern to be\n * recompiled as UTF-8. The function returns FALSE, and sets the\n * RESTART_PASS1 and NEED_UTF8 flags in *flagp, as appropriate. When this\n * happens, the caller needs to desist from continuing parsing, and return\n * this information to its caller. This is not set for when there is only one\n * code point, as this can be called as part of an ANYOF node, and they can\n * store above-Latin1 code points without the pattern having to be in UTF-8.\n *\n * For non-single-quoted regexes, the tokenizer has resolved character and\n * sequence names inside \\N{...} into their Unicode values, normalizing the\n * result into what we should see here: '\\N{U+c1.c2...}', where c1... are the\n * hex-represented code points in the sequence. This is done there because\n * the names can vary based on what charnames pragma is in scope at the time,\n * so we need a way to take a snapshot of what they resolve to at the time of\n * the original parse. [perl #56444].\n *\n * That parsing is skipped for single-quoted regexes, so we may here get\n * '\\N{NAME}'. This is a fatal error. These names have to be resolved by the\n * parser. But if the single-quoted regex is something like '\\N{U+41}', that\n * is legal and handled here.
