[PATCH 02/17] tsearch.3: SYNOPSIS: Use 'restrict' in prototypes

[Alejandro Colomar <alx.manpages@gmail.com>]

Both POSIX and glibc use 'restrict' in tdelete().
Let's use it here too.

.../glibc$ grep_glibc_prototype tdelete
misc/search.h:138:
extern void *tdelete (const void *__restrict __key,
		      void **__restrict __rootp,
		      __compar_fn_t __compar);
.../glibc$
