Subject: eu-stacktrace WIP: include sysprof-capture-types.h
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ac387efd0a863043149a33b0c2b261ffb217a70e;p=thirdparty%2Felfutils.git

eu-stacktrace WIP: include sysprof-capture-types.h

This header defines the Sysprof data format; we could make it optional
through configury, but for now the prototype does not support any other
data format.
