Subject: [PATCH] fix: Build with glibc 2.43

Several glibc functions now return a const pointer if the input is a const pointer and a non-const pointer if the input is non-const, causing a build failure.

Fix this by declaring the output pointers as const if they are never modified and for the lone failure where the output is modified instead make the input non-const.
