rtcGetDev...orMessage(3)

💖 rtcGetDeviceLastErrorMessage — the manual page, bestie edition 💖

okay so you're reading rtcGetDev...orMessage(3) from the Embree Ray Tracing Kernels 4 docs. section 3, the library-functions girlies. let's get into it 🎀

✨ NAME ✨

rtcGetDeviceLastErrorMessage</p> — hands you a message that matches the last error code. it's giving "here's the tea on what just went wrong" 🫶

🌸 SYNOPSIS 🌸

#include <embree4/rtcore.h>

const char* rtcGetDeviceLastErrorMessage(RTCDevice device);

🦋 DESCRIPTION 🦋

so basically, you call this function to get a message that corresponds to the last error code (the one you got back from rtcGetDeviceError), and that message usually spills the details about what actually happened. very demure, very informative. ✨

it's the exact same message that gets written to console when verbosity is > 0, and it's also the same one passed as the str argument of the RTCErrorFunction (go peek at [rtcSetDeviceErrorFunction]). same message, three places. icon behavior. 💅

but here's the part you actually need to know: when device construction fails, this is literally the only way to get extra info about the error. no cap. in that case, rtcNewDevice returns NULL as the device. so to query the error message for a failed device construction, you pass NULL as the device to rtcGetDeviceLastErrorMessage. 🫡

for all other invocations of rtcGetDeviceLastErrorMessage, you must specify a proper device pointer. not optional. no vibes-based shortcuts. 😭

👑 EXIT STATUS 👑

returns a message corresponding to the last error code. periodt. 💖
