* arc4random(3): fix .Xr issuesEnji Cooper2020-12-111-2/+2
| | | | | | | | | | | | | - pthreads(3) should actually be pthread(3). - getentropy(2) should actually be getentropy(3). This makes the manpage `make manlint` clean. MFC after: 1 week Sponsored by: DellEMC Isilon Notes: svn path=/head/; revision=368532
* Sync with OpenBSD:Xin LI2020-04-131-3/+5
| | | | | | | | | | | | | | | | | | arc4random.c: In the incredibly unbelievable circumstance where _rs_init() fails to allocate pages, don't call abort() because of corefile data leakage concerns, but simply _exit(). The reasoning is _rs_init() will only fail if someone finds a way to apply specific pressure against this failure point, for the purpose of leaking information into a core which they can read. We don't need a corefile in this instance to debug that. So take this "lever" away from whoever in the future wants to do that. arc4random.3: reference random(4) arc4random_uniform.c: include stdint.h over sys/types.h Notes: svn path=/head/; revision=359849

* Globally replace u_int*_t from (non-contributed) man pages.Ed Schouten2012-02-121-3/+3
| | | | | | | | | | | | | | The reasoning behind this, is that if we are consistent in our documentation about the uint*_t stuff, people will be less tempted to write new code that uses the non-standard types. I am not going to bump the man page dates, as these changes can be considered style nits. The meaning of the man pages is unaffected. MFC after: 1 month Notes: svn path=/head/; revision=231564
