makes pointer from integer without a cast ?

what does the following message mean?

warning: ..... 'strncpy' makes pointer from integer without a cast

I try to fix the code myself so i will learn better, but i just don't understand some messages that the compiler spits out.

Thanks

It means you have directly assigned the value of a integer to a pointer,
you probaility as in 99.999% of the time you want to assign the address of the integer to the pointer,

e.g.

ptrMyPointer = &MyInteger

& gives the address of the variable,

instead of ptrMyPointer = MyInteger which should give back nonsense more or less.

strncpy() takes two strings and an int as its parameters, you can see that in its man page:

"char *strncpy(char *dest, const char *src, size_t n);"

Maybe you have an int as the first or second parameter?

Are you trying to copy/convert a number into a string. If so, check out sprintf() instead if strncpy().
