Function dfs_mnt_create

components/dfs/dfs_v2/src/dfs_mnt.c:52–71

* @brief Create a new dfs_mnt structure instance. * * This function allocates memory to create a new dfs_mnt structure instance and initializes it. * If the memory allocation is successful, it copies the input path string into the instance and initializes related lists and flags. * * @param[in] path The path string to be mounted. This path information will be copied to the newly created dfs_m

 *         if the memory allocation fails, returns RT_NULL.
