apm_get_power_status(9)

okay so bestie, welcome to apm_get_power_status(9) from the Kernel API Manual — the little kernel API page about grabbing the current power state. no cap, it's giving hardware gossip and I'm obsessed. 💖

🌸 NAME 🌸

apm_get_power_status — get current power state

✨ SYNOPSIS ✨

int apm_get_power_status (u_short *status , u_short *bat , u_short *life );

that's the signature, bestie: it returns an int and takes three pointers to u_short. the way that C just loves a pointer... 💅

🎀 ARGUMENTS 🎀

• status — returned status. that's the assignment, periodt.
• bat — battery info. iconic.
• life — estimated life. we love an estimate.

💖 DESCRIPTION 💖

okay so this one obtains the current power status from the APM BIOS. (yes, APM BIOS — we are in kernel-land, bestie.) We return a status that gives the rough battery status and the current power source. The returned bat value gives an estimate as a percentage of life and a status value for the battery. The estimated life, if it's reported, is a lifetime in seconds/minutes at current power consumption. literally all the power tea. 🔥
