ngx_regex_create_conf

定義在?src/core/ngx_regex.c

static void *
ngx_regex_create_conf(ngx_cycle_t *cycle)
{ngx_regex_conf_t    *rcf;ngx_pool_cleanup_t  *cln;rcf = ngx_pcalloc(cycle->pool, sizeof(ngx_regex_conf_t));if (rcf == NULL) {return NULL;}rcf->pcre_jit = NGX_CONF_UNSET;cln = ngx_pool_cleanup_add(cycle->pool, 0);if (cln == NULL) {return NULL;}cln->handler = ngx_regex_cleanup;cln->data = rcf;rcf->studies = ngx_list_create(cycle->pool, 8, sizeof(ngx_regex_elt_t));if (rcf->studies == NULL) {return NULL;}ngx_regex_studies = rcf->studies;return rcf;

ngx_regex_create_conf?函數是 Nginx 的一部分，用于創建正則表達式的配置結構體?ngx_regex_conf_t

static void *
ngx_regex_create_conf(ngx_cycle_t *cycle)

• 函數聲明：定義一個靜態函數?ngx_regex_create_conf，它接受一個指向?ngx_cycle_t?結構的指針作為參數，并返回一個指向?void?的指針。這里的?cycle?代表當前的 Nginx 運行周期。

{ngx_regex_conf_t    *rcf;ngx_pool_cleanup_t  *cln;

• 變量聲明：聲明兩個指針變量：

  • rcf：指向?ngx_regex_conf_t?結構的指針，用于保存正則表達式的配置信息。

  • cln：指向?ngx_pool_cleanup_t?結構的指針，用于處理內存清理。
