Notes / Warnings

  • This function MUST be called after the µC/HTTP-client Suite Initialization has been completed.

  • If the µC/HTTP-client Asynchronous Task is enabled (HTTPc_CFG_MODE_ASYNC_TASK_EN macro in http-c_cfg.h), the HTTPc Request Object will be added to the request's queue.  

  • If the HTTPc_FLAG_REQ_NO_BLOCK flag is set, the function will be in non-blocking mode. Therefore, the function could return before the HTTP transaction is finished. For the application to be notified when the HTTP transaction completes, the callback function must have been setup before with the parameter type HTTPc_PARAM_TYPE_TRANS_COMPLETE_CALLBACK.
