Anybody know of a situation in which amallinfo would block/spin, and what can be
done to free it up? I'm trying to get some info about memory usage in the
shared arena, but amallinfo never returns from within my program. I've tested
the exact same function in another Performer-based program, and it works fine
there.
Here's the offending function:
void printArenaData(void* arena)
{
struct mallinfo mi;
if(arena)
{
mi = amallinfo(arena); <-- never gets past here
cout << "Total arena memory used: " << mi.arena << endl
<< "\t# of ord. blocks: " << mi.ordblks << endl
<< "\t# of small blks: " << mi.smblks << endl
<< "\t# of holding blks: " << mi.hblks << endl
<< "\tUsed space" << endl
<< "\t Space in holding blk hdrs: " << mi.hblkhd << endl
<< "\t Space in used small blks: " << mi.usmblks << endl
<< "\t Space in used reg. blks: " << mi.uordblks << endl
<< "\tFree space" << endl
<< "\t Small blocks: " << mi.fsmblks << endl
<< "\t Reg. blocks: " << mi.fordblks << endl << endl
<< "Space remaining in arena: " << pfGetSharedArenaSize() -
mi.arena << endl;
}
}
Any ideas?
