Set an attached data pointer to an object with a given string key. 


\begin{DoxyParams}{Parameters}
{\em obj} & The object to attach the data pointer to \\
\hline
{\em key} & The string key for the data to access it \\
\hline
{\em data} & The pointer to the data to be attached\\
\hline
\end{DoxyParams}
This attaches the pointer {\ttfamily data} to the object {\ttfamily obj}, given the access string {\ttfamily key}. This pointer will stay \char`\"{}hooked\char`\"{} to the object until a new pointer with the same string key is attached with \mbox{\hyperlink{group__Evas__Object__Group__Extras_ga70134a7068c9bff4107a761abe0a2ad4}{evas\+\_\+object\+\_\+data\+\_\+set()}} or it is deleted with \mbox{\hyperlink{group__Evas__Object__Group__Extras_gabcd8fb64a5133c6be642fd8770c8a5c9}{evas\+\_\+object\+\_\+data\+\_\+del()}}. On deletion of the object {\ttfamily obj}, the pointers will not be accessible from the object anymore.

You can find the pointer attached under a string key using \mbox{\hyperlink{group__Evas__Object__Group__Extras_gafbad43015793eda4ae50202c0ce0e652}{evas\+\_\+object\+\_\+data\+\_\+get()}}. It is the job of the calling application to free any data pointed to by {\ttfamily data} when it is no longer required.

If {\ttfamily data} is {\ttfamily N\+U\+LL}, the old value stored at {\ttfamily key} will be removed but no new value will be stored. This is synonymous with calling \mbox{\hyperlink{group__Evas__Object__Group__Extras_gabcd8fb64a5133c6be642fd8770c8a5c9}{evas\+\_\+object\+\_\+data\+\_\+del()}} with {\ttfamily obj} and {\ttfamily key}.

\begin{DoxyNote}{Note}
This function is very handy when you have data associated specifically to an Evas object, being of use only when dealing with it. Than you don\textquotesingle{}t have the burden to a pointer to it elsewhere, using this family of functions.

Return an attached data pointer on an Evas object by its given string key. 


\begin{DoxyParams}{Parameters}
{\em obj} & The object to which the data was attached \\
\hline
{\em key} & The string key the data was stored under \\

\end{DoxyParams}
\begin{DoxyReturn}{Returns}
The data pointer stored, or {\ttfamily N\+U\+LL} if none was stored
\end{DoxyReturn}
This function will return the data pointer attached to the object {\ttfamily obj}, stored using the string key {\ttfamily key}. If the object is valid and a data pointer was stored under the given key, that pointer will be returned. If this is not the case, {\ttfamily N\+U\+LL} will be returned, signifying an invalid object or a non-\/existent key. It is possible that a {\ttfamily N\+U\+LL} pointer was stored given that key, but this situation is nonsensical and thus can be considered an error as well. {\ttfamily N\+U\+LL} pointers are never stored as this is the return value if an error occurs.
