Task control block
Loops. Ansible offers the loop, with_<lookup>, and until keywords to execute a task multiple times. Examples of commonly-used loops include changing ownership on several files and/or directories with the file module, creating multiple users with the user module, and repeating a polling step until a certain result is reached. Thread control block. Thread Control Block ( TCB) is a data structure in an operating system kernel that contains thread -specific information needed to manage the thread. [1] The TCB is "the manifestation of a thread in an operating system." Each thread has a thread control block.

A Task Control Block (TCB) is a data structure used by the operating system to manage and keep track of information about a process or thread. It contains important details such as: Process State: Whether the process is ready, running, waiting, etc. Process Privileges: Access levels of the process. Process …This function can be used by cyclical tasks to ensure a constant execution frequency. This function differs from vTaskDelay () in one important aspect: vTaskDelay () will cause a task to block for the specified number of ticks from the time vTaskDelay () is called. It is therefore difficult to use vTaskDelay () by itself to generate a fixed ...Loops. Ansible offers the loop, with_<lookup>, and until keywords to execute a task multiple times.
