Macro Definition Documentation

CTX_ADDR_LEN

#define CTX_ADDR_LEN

Value:

(sizeof(void*) / sizeof(int) +       \
   !!(sizeof(void*) % sizeof(int)))

Many integers are needed to store a pointer.

This is a bit paranoid about sizeof(smx_ctx_sysv_t) not being a multiple of sizeof(int), but it doesn't harm.

simgrid_makecontext()

static void simgrid_makecontext ( ucontext_t *  ucp, void(*)(int first,...)  func, void *  arg  )

static

A better makecontext.

Makecontext expects integer arguments, we the context variable is decomposed into a serie of integers and each integer is passed as argument to makecontext.
