* @brief Retrieve an instance of a blob for use in a program.

* @param obj The binary blob to retrieve an instance of.
|
|
* @return A pointer to an instance of the string on success.

* @c NULL on failure.

|
|
* This macro retrieves an instance of @p obj. If @p obj is
|
|
* @c NULL, then @c NULL is returned. If @p obj is already stored, it
|
|
* is just returned and its reference counter is increased. Otherwise
|
|
* it is added to the blobs to be searched and a duplicated blob
|
|
* of @p obj is returned.
|
|
*
|
|
* This macro essentially calls eina_binshare_add_length with ptr and sizeof(*ptr)
|
|
* as the parameters. It's useful for pointers to structures.
