ngx_process_options是初始化init_cycle中的一些如: conf_file,prefix,conf_prefix等字段的功能, 其方法的定義在src/core/nginx.c中, 以下為詳細**:
主要功能是將ngx_prefix, 配置檔案的位置資訊, 以及命令列引數的資訊初始化到cycle物件中。
static ngx_int_tngx_process_options(ngx_cycle_t *cycle)
ngx_memcpy(p, ngx_prefix, len);
p[len++] = '/'; // 最後還是新增上路徑分割符'/'
}cycle->conf_prefix.len = len;
cycle->conf_prefix.data = p;
cycle->prefix.len = len;
cycle->prefix.data = p;
} else
if (ngx_getcwd(p, ngx_max_path) == 0)
len = ngx_strlen(p);
p[len++] = '/';
cycle->conf_prefix.len = len;
cycle->conf_prefix.data = p;
cycle->prefix.len = len;
cycle->prefix.data = p;
#else
#ifdef ngx_conf_prefix
ngx_str_set(&cycle->conf_prefix, ngx_conf_prefix);
#else
ngx_str_set(&cycle->conf_prefix, ngx_prefix);
#endif
ngx_str_set(&cycle->prefix, ngx_prefix);
#endif
}// 配置檔案資訊初始化到cycle物件
if (ngx_conf_file) else
if (ngx_conf_full_name(cycle, &cycle->conf_file, 0) != ngx_ok)
for (p = cycle->conf_file.data + cycle->conf_file.len - 1;
p > cycle->conf_file.data;
p--)
}// 命令列引數初始化到cycle物件
if (ngx_conf_params)
if (ngx_test_config)
return ngx_ok;
}
