c: iterate an array of structs

kpachopoulos · 08-15-2006, 05:09 AM

Hi,
i have a pointer to an array of (dirent) structs -struct dirent ***namelist. I want to read each struct after another. Can i do "*namelist[i]" for i=1,2,...? Or do i have to something like
"(**namelist)+sizeof(dirent)" to read the next entry of the array? Please explain and clear out what i have written, because there is a confusion in my head...

Thanks

Both methods are correct (I'm not sure why you need ***, but that's another story). They have the same effect.

the second one would work as is, the first would need an extra set of parens to correctly derefernce the ptr to the array, since [] has higher precedence than *..

(*namelist)[i]
