[v2,0/7] New libtracefs APIs

Message

Tzvetomir Stoyanov (VMware) Jan. 12, 2021, 9:20 a.m. UTC

Added new APIs to tracefs library and updated man pages and unit tests:
  tracefs_instance_file_read_number();
  tracefs_instance_file_open();
  tracefs_trace_is_on();
  tracefs_trace_on();
  tracefs_trace_off();
  tracefs_trace_on_get_fd()p;
  tracefs_trace_on_fd();
  tracefs_trace_off_fd();

v2 changes:
 - Renamed tracefs_instance_file_read_int() to tracefs_instance_file_read_number().
 - Added new tracefs_trace_on_get_fd() API.
 - Better error checking of tracefs_instance_file_read_number() API.
 - A few code clean-ups, suggested by Steven.
