◆ vlc_objres_new()

void * vlc_objres_new ( size_t  size,
void(*)(void *)  release 
)

Allocates an object resource.

Parameters
sizestorage size in bytes of the resource data
releasecallback to release the resource
Returns
a pointer to the (uninitialized) storage space, or NULL on error

◆ vlc_objres_push()

void vlc_objres_push ( vlc_object_t obj,
void *  data 
)

Pushes an object resource on the object resources stack.

Parameters
objobject to allocate the resource for
dataresource base address (as returned by vlc_objres_new())

◆ vlc_objres_remove()

void vlc_objres_remove ( vlc_object_t obj,
void *  data,
bool(*)(void *, void *)  match 
)

Releases one object resource explicitly.

If a resource associated with an object needs to be released explicitly earlier than normal, call this function. This is relatively slow and should be avoided.

Parameters
objobject whose resource to release
dataprivate data for the comparison function
matchcomparison function to match the targeted resource
