Subject: Fix return code of write_file()
X-Git-Url: https://git.librecmc.org/?p=oweals%2Fucert.git;a=commitdiff_plain;h=afc86f352bf7915f81e9d38949e91306542aadee

Fix return code of write_file()

write_file() returns 1/true on success; it should return 0/false when
opening the file fails.

To make it more obvious that is function returns true and not 0 on
success, also change its return type to bool.
