Description: Library providing a threading pool where you can add work on the fly. The number
|
||
|
|
of threads in the pool is adjustable when creating the pool. In most cases
|
||
|
|
this should equal the number of threads supported by your cpu.
|
||
|
|
|
||
|
|
For an example on how to use the threadpool, check the main.c file or just read
|
||
|
|
the documentation found in the README.md file.
|
||
|
|
|
||
|
|
In this header file a detailed overview of the functions and the threadpool's logical
|
||
|
|
scheme is presented in case you wish to tweak or alter something.

Description: Jobs are added to the job queue. Once a thread in the pool
|
||
|
|
is idle, it is assigned with the first job from the queue(and
|
||
|
|
erased from the queue). It's each thread's job to read from
|
||
|
|
the queue serially(using lock) and executing each job
|
||
|
|
until the queue is empty.
