Subject: basic/random-util: add new header for getrandom()
X-Git-Tag: chiark/234.4-1+devuan1.1+iwj1~163
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;ds=sidebyside;h=28f5f07114eaa10d1ebcd46efbebcb05a7c51470;p=elogind.git

basic/random-util: add new header for getrandom()

There's some confusion: older man pages specify that linux/random.h
contains getrandom, but newer glibc has it in sys/random.h. Detect if
the newer header is available and include it. We still need the older
header for the flags.
