I don`t know how to make a more specific description because of my
poor english. What i mean about VOD is video-processing module in
CDN provider, this scenario usually be asked to provide parameter
parsing which support seconds and milliseconds. I am developing a
series of moudles which are a bit like nginx-vod-module and new
function will be used based on my experience. I just think the usage
of atofp() is very limited, maybe a function supporting optional mode
should be provided. Anyway, the point is whether other modules
need new function, i pointed out the scene i familiar with and hope
this helps.
