You probably have an old version of the manual page. The current manual
page documents POSIX.1-2024:
$ man -w reallocarray \
| MANWIDTH=64 xargs mansectf STANDARDS \
| head -n11;
malloc(3) Library Functions Manual malloc(3)
STANDARDS
malloc()
free()
calloc()
realloc()
C23, POSIX.1‐2024.
reallocarray()
POSIX.1‐2024.
This was documented in
b9ebd195 (2025-07-20; "man/man3/malloc.3: STANDARDS, HISTORY, BUGS: Clarify (non)conformance of realloc{,array}(3)").
That commit was part of man-pages-6.15:
$ git describe --contains b9ebd195
man-pages-6.15~1
Which was released 10 months ago:
