u The unix ucontext functions are newer and not implemented in older |
| 30 |
|
|
unices (or broken libc's like glibc-2.2.2 and below). They allow very |
| 31 |
|
|
fast coroutine creation and fast switching, and, most importantly, are |
| 32 |
|
|
very stable. |
| 33 |
|
|
|
| 34 |
|
|
s If the ucontext functions are not working or you don't want |
| 35 |
|
|
to use them for other reasons you can try a workaround using |
| 36 |
|
|
setjmp/longjmp/sigaltstack (also standard unix functions). Coroutine |
| 37 |
|
|
creation is rather slow, but switching is very fast as well (often much |
| 38 |
|
|
faster than with the ucontext functions). Unfortunately, glibc-2.1 and |
| 39 |
|
|
below don't even feature a working sigaltstack. |
| 40 |
|
|
|
| 41 |
|
|
l Older GNU/Linux systems (glibc-2.1 and below) need this hack. Since it is |
| 42 |
|
|
very linux-specific it is also quite fast; when it works, that is. |
