tapset::errno — systemtap errno tapset 🦋

🌸 DESCRIPTION 🌸

okay so this tapset is four little helper functions that all have something to do with error codes and return values, and every single one of them has its own full page. no gatekeeping here, we link out. 💅

🫶 errno_str

Symbolic string associated with error code ⭐

See function::errno_str(3stap) for details.

🫶 returnval

Possible return value of probed function 🔥

See function::returnval(3stap) for details.

🫶 returnstr

Formats the return value as a string ✨

See function::returnstr(3stap) for details.

🫶 return_str

Formats the return value as a string 💜

See function::return_str(3stap) for details.

ngl bestie, returnstr and return_str sound the same and do the same thing on the tin — but they are two separate functions with two separate pages, so don't go merging them in your head, iykyk. 🙈
