[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2 1/3] libxl: re-name libxl__xs_write() to libxl__xs_printf()...
...to denote what it actually does. The name libxl__xs_write() suggests something taking a buffer and length, akin to write(2), whereas the semantics of the function are actually more akin to printf(3). This patch is a textual substitution of libxl__xs_write with libxl__xs_printf with some associated formatting fixes.
