- *  @brief     Copies the contents of a memory buffer into another
- *  @param[in] pvTarget the target buffer to which the data is copied into
- *  @param[in] pvSource pointer to the second memory location
- *  @param[in] u32Count the size of the data to copy
- *  @return    WILC_SUCCESS if copy is successfully handeled
- *              WILC_FAIL if copy failed
- *  @note      this function repeats the functionality of standard memcpy,
- *              however memcpy is undefined if the two buffers overlap but this
- *              implementation will check for overlap and report error
