typedef void(* MHD_LogCallback) (void *cls, const char *fm, va_list ap) |
Type of a callback function used for logging by MHD.
cls | closure |
fm | format string (printf() -style) |
ap | arguments to fm |

typedef void(* MHD_PanicCallback) (void *cls, const char *file, unsigned int line, const char *reason) |
Callback for serious error condition. The default action is to print an error message and abort()
.
cls | user specified value |
file | where the error occured |
line | where the error occured |
reason | error detail, may be NULL |

Sets the global error handler to a different implementation. cb will only be called in the case of typically fatal, serious internal consistency issues. These issues should only arise in the case of serious memory corruption or similar problems with the architecture. While cb is allowed to return and MHD will then try to continue, this is never safe.
The default implementation that is used if no panic function is set simply prints an error message and calls abort()
. Alternative implementations might call exit()
or other similar functions.

cls | passed to cb |
