Subject: [PATCH v17 15/18] trace-cmd: Refactor few trace-cmd internal functions.
Date: Tue,  3 Dec 2019 12:35:19 +0200
Message-ID: <20191203103522.482684-16-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20191203103522.482684-1-tz.stoyanov@gmail.com>

In order to reuse code inside trace-cmd application context,
few functions are made non static:
	int make_vsock(unsigned int port);
	int get_vsock_port(int sd, unsigned int *port);
	int open_vsock(unsigned int cid, unsigned int port);
	char *get_guest_file(const char *file, const char *guest);
