Note 4 in the _Typographical Conventions_ section in the frontmatter:

"Names surrounded by braces represent symbolic limits or configuration
values which may be declared in appropriate headers by means of the C
#define construct."

Note that POSIX does not require IOV_MAX to be defined in <limits.h>;
if it isn't, the value of sysconf(_SC_IOV_MAX) should be used instead.
