Subject: Port getprogname() to AIX
X-Git-Tag: 0.11.8~26
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9fa06763a1afe0946a3a20e5bbdba72885cbade5;p=thirdparty%2Flibbsd.git

Port getprogname() to AIX

Get the program name from the COMM field from the proc filesystem.

We could use instead the information from the psinfo binary file under
/proc, but that seems to have a shorter string limit.
