Hi I'm having trouble trying to initializing each element of the struct array. When I try and assign the value ZERO to both 'bSize' and 'msgs', it doesn't work as it errors out when i get to malloc. In the printf statement it prints a -1852803823 number. Excuse the messy code as i'm playing around trying to figure it out.
struct message{
int *data;
int bSize;
int msgs;
};
int main(int argc, char *argv[]) {
.....
}
void getSchedFile (FILE *file, int **schd) {
struct message sMsg[nodeCount];
const int pakSize = 6;
// Iniitialise message buffer
for (int i=0; i<nodeCount; i++){
sMsg[i].bSize = 0;
sMsg[i].msgs = 0;
printf("bSize %d\n",sMsg[i].bSize);
}
/* Get the number of bytes */
fseek(file, 0L, SEEK_SET);
int time;
while((fscanf(file, "%d", &time)) != EOF){
int src;
fscanf(file, "%d", &src); // get source node id
// These are here for easier reading code
int aPos = sMsg[src].bSize;
int nMsg = sMsg[src].msgs;
printf("size %d\n", sMsg[src].bSize);
if (sMsg[src].bSize==0){
sMsg[src].data = malloc( pakSize * sizeof(int));
}else{
sMsg[src].data = realloc(sMsg[src].data, (aPos+pakSize)*sizeof(int));
}
