Dynamically allocate a string matrix in C using struct
0
I've created a code that reads line by line from a file and stores all the data in a string matrix allocated using structs. But I have a memory problem. Here is the code:
struct MyStruct
{
char **cuvinte;
int nr_cuvinte;
char *linie;
};
int function(struct MyStruct **text, FILE *p, char *filename) {
int i = 0;
char buff[1024];
text = NULL;
while (!feof(p))
{
fgets(buff, 1024, p);
int j = 0;
if (text== NULL)
text= (struct MyStruct **)malloc(sizeof(text)*(i + 1));
else {
text= (struct MyStruct **)realloc(text, sizeof(struct MyStruct)*(i + 1));
}
/*
text[i]->linie = (char *)malloc(strlen(buff)+1);
strcpy(text[i]->linie, buff);*/
char *p = strtok(buff, " ");
text[i]->cuvinte = NULL;
while (p)
{
if (text[i]->cuvinte == NULL)
text[i]->cuvinte = (char **)malloc(sizeof(char *));
else
{
text[i]->cuvinte = (char **)realloc(text[i], sizeof(char *)*(j + 1));
}
text[i]->cuvinte[j] = _strdup(p);
text[i]->nr_cuvinte++;
j++;
p = strtok(NULL, " ");
}
i++;
}
int nr_linii = i-1;
return nr_linii;
}

Firstly, you haven't told us what the memory problem is. Even if you did, if the problem renders the program unusable, it's off-topic for this site and you need to instead post to StackOverflow.
