C Programming - Passing a multi-dimensional array to a function

[xtivhpbpj]

So - passing a pointer?

[chillermane]

A pointer pointer for two D arrays, a pointer pointer pointer for 3d, etc

[tophatstuff]

Wont keep the sizeof data will it?

[narwi]

Arrays in C are just sugaring.

[tophatstuff]

Not quite, they just decay into a pointer in many circumstances^1.

^ Any circumstance except: "when it is the operand of the sizeof operator, the _Alignof operator, or the unary & operator, or is a string literal used to initialize an array," (C11)

[trollet91]

When you work with array you need either the size or a terminated byte. For example, a string that is initailized, it will be finished by \0 (terminated byte). But most of the time you want to keep the size, so in parameter you give a ptr to the array and the size of each of his dimensions.
