# SYNOPSIS

|
|
|
|
|

|
|
// purely increasing stats

|
|
|
|
uint64_t failed_renders; // aborted renders, should be 0
|
|
|
|
uint64_t render_bytes; // bytes emitted to ttyfp
|
|
|
|
int64_t render_max_bytes; // max bytes emitted for a frame
|
|
|
|

|
|
|
|

|
|
|
|

|
|
|
|
int64_t render_min_ns; // min ns spent rendering
|
|
|
|
uint64_t cellelisions; // cells elided entirely
|
|
|
|
uint64_t cellemissions; // cells emitted
|
|
|
|
uint64_t fgelisions; // RGB fg elision count
|
|
|
|
uint64_t fgemissions; // RGB fg emissions
|

# DESCRIPTION
|
|
|
|
|
|
|
|
**notcurses_stats** acquires an atomic snapshot of statistics, primarily
|
|
|
|
related to notcurses_render(3). **notcurses_reset_stats** does the same, but
|
|
|
|
also resets all cumulative stats (immediate stats such as **fbbytes** are not
|
|
|
|
reset).
|
|
|
|
|
|
|
|
# NOTES
|
|
|
|
|
|
|
|
Unsuccessful render operations do not contribute to the render timing stats.
|
|
|
|
|
|
|
|
# RETURN VALUES
|
|
|
|
|
|
|
|
Neither of these functions can fail. Neither returns any value.
