X-Git-Tag: v1.16.0-alpha1~31 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1bd5a60c75a778cb81622cce3ed53db70d2e89aa;p=platform%2Fupstream%2Fefl.git eio: improve documentation. This set of documentation update basically make it clearer that Eio use Eina and do cross linking of function used by Eio to Eina. It also copy some of the warning coming from Eina documentation into Eio. --- diff --git a/src/lib/eio/Eio.h b/src/lib/eio/Eio.h index 7b4410f..7ee29fe 100644 --- a/src/lib/eio/Eio.h +++ b/src/lib/eio/Eio.h @@ -142,6 +142,8 @@ extern "C" { * Recommended reading: * * @li @ref Eio_Helper for common functions and library initialization. + * @li @ref Eio_List for listing files asynchronous. + * @li @ref Eio_Management for anyone who want to do a file manager (copy, rm, ...). * @li @ref Eio_Map to manipulate files asynchronously (mmap). * @li @ref Eio_Xattr to access file extended attributes (xattr). * @li @ref Eio_Monitor to monitor for file changes (inotify). @@ -153,7 +155,6 @@ extern "C" { * * More examples can be found at @ref eio_examples. * - * @{ */ /** @@ -185,6 +186,18 @@ enum _Eio_File_Op typedef enum _Eio_File_Op Eio_File_Op; /** + * @defgroup Eio_List Eio file listing API + * @ingroup Eio + * + * @brief This functions helps list files asynchronously. + * + * This set of functions work on top of Eina_File and Ecore_Thread + * to list files under various condition. + * + * @{ + */ + +/** * @typedef Eio_File * Generic asynchronous I/O reference. */ @@ -252,14 +265,20 @@ struct _Eio_Progress * It's equivalent to the "ls" shell command.
