err_msg(9) β Kernel API Manual (yes bestie, that's the 9 section, we're in kernel-land now)
okay so picture this: you're deep in the kernel tooling, something goes sideways, and you need to yell about it β politely, to stderr. That's literally the whole gig of err_msg. It's the friend who taps you on the shoulder and goes "girlβ¦ it broke." π«Ά
β¨ NAME β¨

π SYNOPSIS π
void err_msg (const char *fmt , ... );
πΈ ARGUMENTS πΈ
fmtβ honestly?-- undescribed --. the manpage itself is giving mysterious main character energy and refusing to elaborate π that's not me gatekeeping, that's literally what's written....β variable arguments π« the whole "however many extras you feel like" situation.
π¦ SEE ALSO π¦

./tools/verification/rv/src/utils.cβ that's where this lives, go snoop π debug_msg(9)β its sibling, for when you want to say things without the error vibes π
ngl, this one is short and sweet, but thatfmtbeing-- undescribed --is sending me π it's in the original, we don't fix what the kernel wrote, periodt.
