kandi X-RAY | libtask Summary
libtask is a simple coroutine library. it runs on linux (arm, mips, and x86), freebsd (x86), os x (powerpc x86, and x86-64), and sunos solaris (sparc), and is easy to port to other systems. libtask gives the programmer the illusion of threads, but the operating system sees only a single kernel thread. for clarity, we refer to the coroutines as "tasks," not threads. scheduling is cooperative. only one task runs at a time, and it cannot be rescheduled without explicitly giving up the cpu. most of the functions provided in task.h do have the possibility of going to sleep. programs using the task functions should #include . --- basic task manipulation. int taskcreate(void (*f)(void *arg), void *arg, unsigned int stacksize);. void taskmain(int argc, char *argv[]);. int taskdelay(unsigned int ms). void taskstate(char*, ...); char* taskgetstate(void);. there is a small amount of runtime support for non-blocking i/o on file descriptors. int fdread(int, void*, int);. int fdwrite(int, void*, int);. void fdwait(int fd, int rw);. these are convenient packaging of the ugly unix socket routines. they can all put the current task

QUESTION
I tried to build task-2.5.1 on my armv81 chromebook inside a termux session. It didn't work due build dependencies so I installed them then uncompressed and started in a fresh new directory. When I ran make VERBOSE=1
I got an undefined reference to __atomic_fetch_add_4
when linking...
