Where is c++ size_t defined in linux
<p>Now I'm talking about new type definition by a programmer using typedef keyword. As long as my pupils are used to the type size_t (for example by using funciton length ()), for which I had to ask them a little effort to just "believe" it is an integer type, I think it woud be great to show noew them where this type is defined.</p>

<p>So, I've done a lot grep's in /usr/include in an ubuntu box, and what I see is that size_t is, in turn, a redefinition of size_type wich in turn is a redefinition of metadata_type, and that's the end in this directory. Not found the final "typedef unsigned int metadata_type;".</p>

<p>In /usr/src I've found anohter previous type called yy_size_t,...</p>

<p>But, in any case I've been unable the get to the end of the chain.</p>

<p>Does anyone know where to find out the final definition to check out that it is an unsigned int (or the like)?
May be I miss a development package in my box? In this case, why I'm able to compile programs using size_t type?</p>
