As I am trying to touch as few source files as possible I am looking for a
good way to substitute a call to Linux kzalloc(). This function allocates
and zeroes the memory before returning the pointer. So a call to malloc()
and then memset() in eCos is my approach.
How can a #define be written to do the trick, so I don't need to touch the
source file in this area with #ifdef __ECOS ?
struct jffs2_inode_info *f = kzalloc(sizeof(*f), GFP_KERNEL);
if (!f)
return -ENOMEM;
#define kzalloc(x,y) \
malloc(x); \
if (HOW_TO_MAKE_SURE_MALLOC_WAS_SUCCESSFUL) { \
memset(tmp,0,x);\
}
Regards
