[ECOS] [eCos] a question about ROMFS

["jjtsai" <jjtsai at itri dot org dot tw>]

Hi,

    I have a question about ROM files system.

 

[Question Description]

    A fseek(,,SEEK_CUR) after fread() will cause inconsistency between "(CYG_StdioStream) real_stream.position"

    and "fp->f_offset". See also stream.inl and rom_fs.c.

   

    Here is my test program. See attchment: fseek_test.c .

 

[My modfication]

 

See attachment: stream_inl_patch.pat.

Instruction about how to apply it:

cd $(ECOS_REPOSITORY)/packages/language/c/libc/stdio/current/include
patch -p0 < $(WHERE_THE_PATCH_IS)/stream_inl_patch.pat

regards,
