Helper function bpf_get_current_comm
Definition
Copyright (c) 2015 The Libbpf Authors. All rights reserved.
Copy the comm attribute of the current task into buf of size_of_buf. The comm attribute contains the name of the executable (excluding the path) for the current task. The size_of_buf must be strictly positive. On success, the helper makes sure that the buf is NUL-terminated. On failure, it is filled with zeroes.
Returns
0 on success, or a negative error in case of failure.
