Hi,
Following warnings are generated when compiling mm_core_apis.c:
cc -I../../../../include -Wall mm_core_apis.c -L../../../../lib -lltp
-lmm -o mm_core_apis
mm_core_apis.c: In function ‘mm_core_test01’:
mm_core_apis.c:110: warning: pointer targets in assignment differ in
signedness
mm_core_apis.c: In function ‘mm_core_test02’:
mm_core_apis.c:202: warning: pointer targets in assignment differ in
signedness
Attached path fixes them:
