libconcurrent
=============
[](https://github.com/sharow/libconcurrent/blob/master/LICENSE)
tiny asymmetric-coroutine library.

+ asymmetric-coroutine
+ bidirectional communication by `yield_value`/`resume_value`
+ native context switch
+ C11
## Supported Platforms

## Code Example
```c
#include
#include
#include
#include
#include
#include
#define STACK_SIZE (1024 * 2)
noreturn void accumulator(struct concurrent_ctx *ctx)
{
int *v = ctx_get_resume_value(ctx);
int total = *v;
for (;;) {
v = yield_value(ctx, &total); // send total / receive next value
total += *v;
}
}
int main(void)
{
struct concurrent_ctx *ctx;
uint8_t stack[STACK_SIZE];
uint8_t ctx_alloc[ctx_sizeof()];
concurrent_init();
ctx = (struct concurrent_ctx *)ctx_alloc;
ctx_construct(ctx, stack, STACK_SIZE, accumulator, NULL);
for (int i = 1; i <= 10; i++) {
int *total = resume_value(ctx, &i); // send value / receive total
printf("total = %d\n", *total);
}
ctx_destruct(ctx);
concurrent_fin();
return EXIT_SUCCESS;
}
/*
$ gcc -o sample sample.c -lconcurrent.a
$ ./sample
total = 1
total = 3
total = 6
total = 10
total = 15
total = 21
total = 28
total = 36
total = 45
total = 55
*/
```
## Requirements for build
- for x86_64/i686: [nasm](http://www.nasm.us/)
## Installation
```
$ git clone https://github.com/sharow/libconcurrent.git libconcurrent
$ cd libconcurrent
$ make
$ sudo make install
```
#### for FreeBSD
Available in ports collection as [devel/libconcurrent](http://portsmon.freebsd.org/portoverview.py?category=devel&portname=libconcurrent)
#### for OSX
- install latest [nasm](http://www.nasm.us/) from [brew](http://brew.sh)
```
$ brew install nasm
```
## Tests
```
$ make test
```
