Reprapfirmware size_t confuse

hi all friends, I am reading the source code of Reprapfirmware recently, and when I go through this file "DeltaParameters.h",
I met a data type called "size_t", in this statement: "float GetTower hot smiley

size_t axis) const { return towerX[axis]; }", and it says: "typedef __SIZE_TYPE__ size_t; ",
what type is this "size_t"? where it is defined?

size_t is a platform-dependent C++ type. You need to #include in your source file to get its definition.

aha, thank you david. I found it and it's defined in the "stddef.h" head file, it's simply an unsigned int type. drinking smiley

Sorry my previous post has cstddef in angle brackets after "include" but the forum software seems to have interpreted it as markup so it doesn't show up.
