Question

VOID EXEFunc() { PVOID pv = DLLFunc(); heap free(pv); } PVOID DLLFunc() { heap return(malloc(100)); } hi guys it's written

in the book with quotes below:
"If both the EXE
and the DLL link to the DLL C/C++ run-time library, the code works just fine. However, if one or both of the modules
link to the static C/C++ run-time library, the call to free fails"

it's said that the correct way would be like this:
VOID EXEFunc() {
PVOID pv = DLLFunc();
// Access the storage pointed to by pv...
DLLFreeFunc(pv);
}
PVOID DLLFunc() {
PVOID pv = malloc(100);
return(pv);
}
BOOL DLLFreeFunc(PVOID pv) {
return(free(pv));
}
but i think both almost same
what's the differences?

the book says both malloc and free must be in exe or in dll to work in that context
