Raw Normal View History

fixed a formatting bug in qse_strtonwad() renamed qse_httpd_addserver() to qse_httpd_attachserver(). added qse_httpd_detachserver(). added the predetach field to qse_httpd_server_t. added qse_httpd_cbstd_t and changed qse_htpd_loopstd() to accept this cbstd. enhanced server uri parsing to include 'docroot'. enhanced qse_httpd_entasktext() and added qse_httpd_entask_text() for internal use. added nwif functions like qse_nwifindextombs(). added qse_env_insertmbsa()/qse_env_insertwcsa()/qse_env_inserta(). enhanced TPROXY handling
