问题 To find the load average in linux I use sys/sysinfo.h which include linux/kernel.h, where the following structure is defined: struct sysinfo { long uptime; /* Seconds since boot */ unsigned long loads[3]; /* 1, 5, and 15 minute load averages */ unsigned long totalram; /* Total usable main memory size */ unsigned long freeram; /* Available memory size */ unsigned long sharedram; /* Amount of shared memory */ unsigned long bufferram; /* Memory used by buffers */ unsigned long totalswap; /*

问题 I'm trying to get a Computer System Model type via Batch file. for this i've created this script: systeminfo | find "System Model" > %temp%\TEMPSYSINFO.txt for /F "tokens=2 delims=:" %%a in (%temp%\TEMPSYSINFO.txt) do set SYSMODEL=%%a del %temp%\TEMPSYSINFO.txt set SYSMODEL=%SYSMODEL:~1% echo %SYSMODEL% >%temp%\SYSMODEL.txt del %temp%\SYSMODEL.txt set "Line1=*** System Model: %SYSMODEL%" echo %Line1% but when I run it i get extra spaces: *** System Model: OptiPlex 9010 Any idea how can I fix

sysinfo returns incorrect value for freeram (even with mem_unit)

问题 My full C MATE applet can be found at github here: https://github.com/geniass/mate-resource-applet/tree/cmake (BRANCH CMAKE). It's a hacky mess right now, so see the code below. I couldn't find an applet to display my computer's free ram, so that's basically what this is. I am using sysinfo to get this information, and it works fine for my system's total ram (roughly 4GB, it shows 3954 MB). htop shows 3157 MB used of 3954 MB. However, the value sysinfo gives for free ram (136 MB) is obviously

问题 I have a C program that prints some system statistics. #include <sys/sysinfo.h> #include <stdio.h> int main() { int days, hours, mins; struct sysinfo sys_info; if(sysinfo(&sys_info) != 0) perror("sysinfo"); // Uptime days = sys_info.uptime / 86400; hours = (sys_info.uptime / 3600) - (days * 24); mins = (sys_info.uptime / 60) - (days * 1440) - (hours * 60); printf("Uptime: %ddays, %dhours, %dminutes, %ldseconds\n", days, hours, mins, sys_info.uptime % 60); // Load Averages for 1,5 and 15

You're doing it the hard way. Use wmic . It's a lot faster and less complicated to scrape. for /f

sysinfo system call not returning correct freeram value

问题 I recently wrote the following C code using sysinfo systemcall to display system statistics, what amused me was that the freeram variable of sysinfo structure doesn't return the amount of free RAM instead it is returning the current RAM usage. I had to use a workaround to show the correct value by subtracting freeram from totalram. I have tried googling about this specific variable but to no avail. Any insight into this weird behavior would be really helpful. /* * C program to print the
