[PATCH 14/18] conf: use disk source accessors in vmware/

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Part of a series of cleanups to use new accessor methods.

While writing this, I also discovered that conversion from XML
to vmware modified the disk source in place; if the same code
is reached twice, the second call behaves differently because
the first call didn't clean up its mess.

* src/vmware/vmware_conf.c (vmwareVmxPath): Use accessors.
(vmwareParsePath): Avoid munging input string.
* src/vmware/vmware_conf.h (vmwareParsePath): Make static.
