Syntax

See Syntax for type attributes used on functions.

Description

The __monitor keyword causes interrupts to be disabled during execution of the function. This allows atomic operations to be performed, such as operations on semaphores that control access to resources by multiple processes. A function declared with the __monitor keyword is equivalent to any other function in all other respects.

Example

__monitor int get_lock(void);
