Hi, I am very much stuck in the following issue. Any help is very much appreciated!
Basically I have a program wich contains an array of structs and I am getting a segmentation error when I call an external function. The error only happens when I have more than 170 items on the array being passed.
Nothing on the function is processed. The program stops exactly when accessing the function.
Is there a limit for the size of the parameters that are passed to external functions?
Main.c
Code:
struct ratingObj {
int uid;
int mid;
double rating;
};
void *FunctionLib; /* Handle to shared lib file */
void (*Function)(); /* Pointer to loaded routine */
const char *dlError; /* Pointer to error string */
int main( int argc, char * argv[]){
// ... some code ...
struct ratingObj movies[listSize];
// ... more code ...
FunctionLib = dlopen("dll.so", RTLD_LAZY);
dlError = dlerror();
if( dlError ) exit(1);
Function = dlsym( FunctionLib, "getResults");
dlError = dlerror();
(*Function)( moviesToRate, listSize );
// .. more code
}
library.c
Code:
struct ratingObj {
int uid;
int mid;
double rating;
};
typedef struct ratingObj ratingObj;
void getResults(struct ratingObj *moviesToRate, int listSize);
void getResults(struct ratingObj *moviesToRate, int listSize){
// ... more code
}
