Erik Heckers fixed bug #493 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.

.SH "DESCRIPTION"
.PP
Sets the OpenGL \fIattribute\fR \fBattr\fR to \fBvalue\fR\&. The attributes you set don\&'t take effect until after a call to \fI\fBSDL_SetVideoMode\fP\fR\&. You should use \fI\fBSDL_GL_GetAttribute\fP\fR to check the values after a \fBSDL_SetVideoMode\fP call\&.
.SH "RETURN VALUE"
.PP
Returns \fB0\fR on success, or \fB-1\fR on error\&.
.SH "EXAMPLE"
