/*
Gathers system information on `Windows`, `Linux`, `macOS`, `FreeBSD` & `OpenBSD`.
Simply import the package and you'll have access to the OS version, RAM amount
and CPU information.
On Windows, GPUs will also be enumerated using the registry.
CPU feature flags can be tested against `cpu_features`, where applicable, e.g.
`if .aes in info.cpu_features.? { ... }`
Example:
package main
import "core:fmt"
import si "core:sys/info"
main :: proc() {
fmt.printfln("Odin: %v", ODIN_VERSION)
fmt.printfln("OS: %v", si.os_version.as_string)
fmt.printfln("OS: %#v", si.os_version)
fmt.printfln("CPU: %v", si.cpu.name)
fmt.printfln("CPU cores: %vc/%vt", si.cpu.physical_cores, si.cpu.logical_cores)
fmt.printfln("RAM: %#.1M", si.ram.total_ram)
fmt.println()
for gpu, i in si.gpus {
fmt.printfln("GPU #%v:", i)
fmt.printfln("\tVendor: %v", gpu.vendor_name)
fmt.printfln("\tModel: %v", gpu.model_name)
fmt.printfln("\tVRAM: %#.1M", gpu.total_ram)
}
}
