#define EXTRA_CHECKS MHD_NO |
Should we perform additional sanity checks at runtime (on our internal invariants)? This may lead to aborts, but can be useful for debugging.
Definition at line 52 of file internal.h.
#define MAX_NONCE_LENGTH 129 |
Maximum length of a nonce in digest authentication. 32(MD5 Hex) + 8(Timestamp Hex) + 1(NULL); hence 41 should suffice, but Opera (already) takes more (see Mantis #1633), so we've increased the value to support something longer...
Definition at line 177 of file internal.h.

#define MHD_BUF_INC_SIZE 1024 |
Minimum size by which MHD tries to increment read/write buffers. We usually begin with half the available pool space for the IO-buffer, but if absolutely needed we additively grow by the number of bytes given here (up to – theoretically – the full pool space).

#define MHD_PANIC | ( | msg | ) | do { mhd_panic (mhd_panic_cls, __FILE__, __LINE__, NULL); BUILTIN_NOT_REACHED; } while (0) |
Trigger 'panic' action based on fatal errors.

typedef void*(* LogCallback)(void *cls, const char *uri, struct MHD_Connection *con) |
Signature of function called to log URI accesses.
cls | closure |
uri | uri being accessed |
con | connection handle |
Definition at line 867 of file internal.h.
typedef ssize_t(* ReceiveCallback)(struct MHD_Connection *conn, void *write_to, size_t max_bytes) |
Function to receive plaintext data.
conn | the connection struct |
write_to | where to write received data |
max_bytes | maximum number of bytes to receive |
Definition at line 490 of file internal.h.
typedef ssize_t(* TransmitCallback)(struct MHD_Connection *conn, const void *write_to, size_t max_bytes) |
Function to transmit plaintext data.
conn | the connection struct |
read_from | where to read data to transmit |
max_bytes | maximum number of bytes to transmit |
Definition at line 502 of file internal.h.
typedef size_t(* UnescapeCallback)(void *cls, struct MHD_Connection *conn, char *uri) |
Signature of function called to unescape URIs. See also MHD_http_unescape().
cls | closure |
conn | connection handle |
uri | 0-terminated string to unescape (should be updated) |
Definition at line 880 of file internal.h.
enum MHD_CONNECTION_STATE |
States in a state machine for a connection.
Transitions are any-state to CLOSED, any state to state+1, FOOTERS_SENT to INIT. CLOSED is the terminal state and INIT the initial state.
Note that transitions for reading happen only after the input has been processed; transitions for writing happen after the respective data has been put into the write buffer (the write does not have to be completed yet). A transition to CLOSED or INIT requires the write to be complete.
Definition at line 344 of file internal.h.
What is this connection waiting for?
Definition at line 147 of file internal.h.
enum MHD_EpollState |
State of the socket with respect to epoll (bitmask).
Definition at line 106 of file internal.h.
time_t MHD_monotonic_time | ( | void | ) |
Equivalent to time(NULL)
but tries to use some sort of monotonic clock that isn't affected by someone setting the system real time clock.
