[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [RFC PATCH 1/6] 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.
