我已尽一切努力，并且在StackOverflow上读取每个线程均无济于事。您能帮我理解我在代码中遇到的Valgrind错误吗？
void stringArrayAppend(char** array, int numLines, char* toAppend) {
printf("Size of toAppend: %zu\n", sizeof(toAppend));
printf("Size of character pointer: %zu\n", sizeof(char*));
array = realloc(array, sizeof(char*) * numLines);
if (array == NULL) {
printf("Could not reallocate string array to append string %s\n", toAppend);
freeStringArray(array, numLines);
return;
}
array[numLines - 1] = toAppend;
}
输出：
First element of string upon creation: a
Second element of string upon creation:
Size of string upon creation: 8
