From 46c4540dd2f6181e77b0800a4e007d78d0162487 Mon Sep 17 00:00:00 2001 From: Laslo Hunhold Date: Sat, 19 May 2018 22:52:17 +0200 Subject: Implement fmt_human_2() and fmt_human_10() These functions take the raw number and a unit and automatically print it out "scaled down" to a proper SI-prefix, for powers of 2 and 10 respectively. Apply them to the 2-power cases and keep the 10-power for a later commit. --- components/netspeeds.c | 28 ++++++++++++++++++++-------- 1 file changed, 20 insertions(+), 8 deletions(-) (limited to 'components/netspeeds.c') diff --git a/components/netspeeds.c b/components/netspeeds.c index 32e78d6..f0f7455 100644 --- a/components/netspeeds.c +++ b/components/netspeeds.c @@ -25,9 +25,12 @@ if (pscanf(path, "%llu", &rxbytes) != 1) { return NULL; } + if (oldrxbytes == 0) { + return NULL; + } - return oldrxbytes ? fmt_scaled((rxbytes - oldrxbytes) * - 1000 / interval) : NULL; + return fmt_human_2((rxbytes - oldrxbytes) * + 1000 / interval, "B/s"); } const char * @@ -48,9 +51,12 @@ if (pscanf(path, "%llu", &txbytes) != 1) { return NULL; } + if (oldtxbytes == 0) { + return NULL; + } - return oldtxbytes ? fmt_scaled((txbytes - oldtxbytes) * - 1000 / interval) : NULL; + return fmt_human_2((txbytes - oldtxbytes) * + 1000 / interval, "B/s"); } #elif defined(__OpenBSD__) #include @@ -87,9 +93,12 @@ warn("reading 'if_data' failed"); return NULL; } + if (oldrxbytes == 0) { + return NULL; + } - return oldrxbytes ? fmt_scaled((rxbytes - oldrxbytes) * - 1000 / interval) : NULL; + return fmt_human_2((rxbytes - oldrxbytes) * + 1000 / interval, "B/s"); } const char * @@ -120,8 +129,11 @@ warn("reading 'if_data' failed"); return NULL; } + if (oldtxbytes == 0) { + return NULL; + } - return oldtxbytes ? fmt_scaled((txbytes - oldtxbytes) * - 1000 / interval) : NULL; + return fmt_human_2((txbytes - oldtxbytes) * + 1000 / interval, "B/s"); } #endif -- cgit v1.2.3
