The size of a file

[srg86]

Hi

How do I find out the size of a file is using AmigaDOS calls (I don't think there is anything to do this in the standard C library but I could be wrong).

thanks

dos.library/Examine
dos.library/ExamineFH

Occasionally also code using dos.library/Seek can be seen, but this method is really really slow with FFS and large files, and should be avoided.

You can do it in ANSI-C on an open file like this:

fseek(f, 0, SEEK_END);
size = ftell(f);

the conversion to Amiga function calls I leave as an exercise :-)

greets,
Staf.

If you don't need ANSI-C, use fstat (or stat). Even SAS/C linklibs have it.

I've found Examine, but I can't find what header file ExamineFH is in.

It`s in dos.h , the same as Examine
