Function Documentation
| static int extract_uri_parameters | ( | struct http_state * | hs, |
| char * | params | ||
| ) | [static] |
Extract URI parameters from the parameter-part of an URI in the form "test.cgi?x=y".
- Parameters:
-
hs http connection state params pointer to the NULL-terminated parameter string from the URI
- Returns:
- number of parameters extracted
Definition at line 748 of file lwip_httpd.c.
The connection shall be actively closed.
Reset the sent- and recv-callbacks.
- Parameters:
-
pcb the tcp pcb to reset callbacks hs connection state to free
Definition at line 703 of file lwip_httpd.c.
| static err_t http_close_or_abort_conn | ( | struct tcp_pcb * | pcb, |
| struct http_state * | hs, | ||
| u8_t | abort_conn | ||
| ) | [static] |
The connection shall be actively closed (using RST to close from fault states).
Reset the sent- and recv-callbacks.
- Parameters:
-
pcb the tcp pcb to reset callbacks hs connection state to free
Definition at line 653 of file lwip_httpd.c.
| static void http_eof | ( | struct tcp_pcb * | pcb, |
| struct http_state * | hs | ||
| ) | [static] |
End of file: either close the connection (Connection: close) or close the file (Connection: keep-alive)
Definition at line 712 of file lwip_httpd.c.
| static struct http_ssi_state* http_ssi_state_alloc | ( | void | ) | [static, read] |
Allocate as struct http_ssi_state.
Definition at line 450 of file lwip_httpd.c.
| static void http_ssi_state_free | ( | struct http_ssi_state * | ssi ) | [static] |
Free a struct http_ssi_state.
Definition at line 467 of file lwip_httpd.c.
| static struct http_state* http_state_alloc | ( | void | ) | [static, read] |
Allocate a struct http_state.
Definition at line 490 of file lwip_httpd.c.
| static void http_state_eof | ( | struct http_state * | hs ) | [static] |
Free a struct http_state.
Also frees the file data if dynamic.
Definition at line 520 of file lwip_httpd.c.
| static void http_state_free | ( | struct http_state * | hs ) | [static] |

Definition at line 556 of file lwip_httpd.c.
| static void http_state_init | ( | struct http_state * | hs ) | [static] |
Initialize a struct http_state.
Definition at line 478 of file lwip_httpd.c.
| static err_t http_write | ( | struct tcp_pcb * | pcb, |
| const void * | ptr, | ||
| u16_t * | length, | ||
| u8_t | apiflags | ||
| ) | [static] |
Call tcp_write() in a loop trying smaller and smaller length.
- Parameters:
-
pcb tcp_pcb to send ptr Data to send length Length of data to send (in/out: on return, contains the amount of data sent) apiflags directly passed to tcp_write
- Returns:
- the return value of tcp_write
