Subject: [PATCH 06/21] trace-cmd library: Set long size to the input tep handler when it is read from the file
Date: Fri, 10 Sep 2021 16:47:42 +0300	[thread overview]
Message-ID: <20210910134757.2863982-7-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210910134757.2863982-1-tz.stoyanov@gmail.com>

Setting the long size to the input tep handler in tracecmd_read_headers()
API may be too late, as this tep handler is used to read and parse data
from the file before that. The most suitable place for that is
tracecmd_alloc_fd() API, right after reading the long size from the
file.
