@end macro
@c Document a function as thread safe.

| AS-Safe \comments\

@end macro

@c handlers.  This distinguishes unmarked functions, for which this
@c property has not been assessed, from those that have been analyzed.

@end macro
@c Document a function as safe for use when asynchronous cancellation is
@c enabled.
@macro acsafe {comments}
| AC-Safe \comments\

@end macro
@c Document a function as unsafe for use when asynchronous cancellation
@c is enabled.  This distinguishes unmarked functions, for which this
@c property has not been assessed, from those that have been analyzed.
@macro acunsafe {comments}

@end macro
@c Format safety properties without referencing the section of the
@c definitions.  To be used in the definitions of the properties
@c themselves.
