The analyzer detected a potential error related to an explicit type conversion. An array defined as "type Array[3][4]" is cast to type "type **". This type conversion is most likely to be meaningless.
Types "type[a][b]" and "type **" are different data structures. Type[a][b] is a single memory area that you can handle as a two-dimensional array. Type ** is an array of pointers referring to some memory areas.
Here is an example:
void Foo(char **names, size_t count)
{
for(size_t i=0; i<count; i++)
printf("%s\n", names[i]);
}
void Foo2()
{
char names[32][32];
...
Foo((char **)names, 32); //Crash
}This is the correct code:
void Foo2()
{
char names[32][32];
...
char *names_p[32];
for(size_t i=0; i<32; i++)
names_p[i] = names[i];
Foo(names_p, 32); //OK
