Hi, .ad Begin line adjustment for output lines in current adjust mode. .ad c Start line adjustment in mode c (c=l,r,c,b,n). That looks like left, right, centered, block and neutral? Just my uninformed guess, and I am not at all sure about my impromptu Interpretation of 'n'. Best regards, Oliver.

Branden Robinson Cc: linux-man; groff@xxxxxxx Betreff: .ad l/.ad b Hi, Branden and Michael! I've seen these in shmctl.2, and didn't know what they mean. groff(7) wasn't very helpful. [ .SH SYNOPSIS .nf .ad l .B #include <sys/shm.h> .PP .BI "int shmctl(int " shmid ", int " cmd ", struct shmid_ds *" buf ); .ad b .fi ] What are those '.ad X' and do we really need them? I found some other pages that use it: [ .../linux/man-pages$ grep -rn '^\.ad b' man? man1/localedef.1:60:.ad b man2/setsid.2:40:.ad b man2/acct.2:41:.ad b man2/shmctl.2:55:.ad b man2/shmget.2:50:.ad b ] groff(7) related info: [ .ad Begin line adjustment for output lines in current adjust mode. .ad c Start line adjustment in mode c (c=l,r,c,b,n). ] But what does each mode mean? I couldn't find anything about them in the manual page. Thanks, Alex -- Alejandro Colomar Linux man-pages comaintainer; https://www.kernel.org/doc/man-pages/ http://www.alejandro-colomar.es/
