but it always doesn't work correctly in my programe, dit me forget anything? it's my code: if &#40;mkdir&#40;path, 0777&#41; < 0&#41; &#123; if &#40;errno == ENAMETOOLONG&#41; &#123; return -2; &#125; return -1; &#125; return 0; when I set path as a very long ...

hi TyRaNiD,
I have checked my build.mak after reading your reply.
I have found USE_KERNEL_LIBC and USE_PSPSDK_LIBC, what's the different?how to choose this flag?

In newlib, how many functions can work nice, is there a list like libc/LIB.status?

thank you.

I'm not sure about the relation between pspsdk and newlib right now, so I use sceXXX functions directly.maybe cause the confusion. can you teach me what's the relation ? I only know newlib is encapsulation, provide useful functions , I found newlib-psp directory in the svn, and libc subdirectory in ...

thx TyRaNiD. I made a little change, and test again: first of all, client code hasn't invoke these function, just compiled it and pack to my static lib. 1. std::string Directory::GetCurrentDirectory() { SceUID tid; int rt; char buff[MAXPATHLEN]; tid = sceKernelGetThreadId(); rt = sceIoGetThreadCwd(t...

before is my code: SceUID tid; char buff[MAXPATHLEN]; tid = sceKernelGetThreadId(); sceIoGetThreadCwd(tid, buff, sizeof(buff)); but the game crashed. sceKernelGetThreadId return a int value, I think it's not that sceIoGetThreadCwd needs as the first parameter. anyone knows how to use sceIoGetThreadC...

thanks jimparis.

how to make error thread safe? Can I use TLS?

1.is there a way to know the error string?
example:
I have invoked this method: sceIoGetThreadCwd, and get the return value ret(ret < 0), how to know what's the error reason?

2.is errno in libc thread safe?
