Searching the installed man pages for SDL functions fails, e.g. man -k SDL_ |grep Video After investigating this I found that "makewhatis", the tool that generates the "whatis" database, reads the SDL_* man pages, but doesn't produce entries in the "whatis" database for the SDL_* man pages. After some more debugging I found the reason is a missing space. After editing SDL_Init.3(.gz) and replacing SDL_Init\- Initializes SDL with SDL_Init \- Initializes SDL everything works fine. After running "makewhatis" I can successfully do a man -k SDL_ and SDL_Init is listed in the output. --HG-- branch : SDL-1.2 extra : convert_revision : svn%3Ac70aab31-4412-0410-b14c-859654838e24/branches/SDL-1.2%402660
