Sometimes library functions as well as system calls need to set errno. Depending on whether something is linked with _REENTRANT or not, errno may be per-thread, or global.
libc has internal magic to do the right thing regardless of whether or not what it is dynamically linked to was compiled with _REENTRANT. But it does not appear to make that magic publically available. How could one create a public routine meant to be in a shared (or static) library, that needs to set errno, and do it properly regardless of whether or not what it was linked with set _REENTRANT (and included errno.h)? Anyone know how (or whether) other OSs handle this?
