Hi As indicated in gcc maunal and ld manual, Using "-Wl,--wrap -Wl,wraper_func_name" can provide a wrapper function for certain interface in the program. However, I found this doesn't work for function calls in the shared library. for example, if I use -Wl,--wrap -Wl,malloc to wrap the malloc function, I can wrap the calls to malloc in my code, but the malloc called in library cannot be wrapped. I think this is because --wrap option is managed by linker, while it cannot replace calls to malloc in library with wrapper functions. However, if I want to wrap function calls in library (e.g. memcpy), what should I do? Any hints on this problem is truly appreciated. Andrew
