void vortex_ctx_set_data_full ( VortexCtx ctx,
const char *  key,
axlPointer  value,
axlDestroyFunc  key_destroy,
axlDestroyFunc  value_destroy 
)

Allows to store arbitrary data associated to the provided context, which can later retrieved using a particular key.

It is also possible to configure a destroy handler for the key and the value stored, ensuring the memory used will be deallocated once the context is terminated (vortex_ctx_free) or the value is replaced by a new one.

Parameters:
ctx The ctx where the data will be stored.
key The key to index the value stored. The key must be a string.
value The value to be stored. If the value to be stored is NULL, the function calls to remove previous content stored on the same key.
key_destroy Optional key destroy function (use NULL to set no destroy function).
value_destroy Optional value destroy function (use NULL to set no destroy function).
