Ada 2005 Reference Manual
H.5 Pragma Detect_Blocking
The following pragma forces an implementation to detect potentially blocking operations within a protected operation.
Syntax
The form of a pragma Detect_Blocking is as follows:
pragma Detect_Blocking;
Post-Compilation Rules
A pragma Detect_Blocking is a configuration pragma.
Dynamic Semantics
An implementation is required to detect a potentially blocking operation within a protected operation, and to raise Program_Error (see 9.5.1).
Implementation Permissions
An implementation is allowed to reject a compilation_unit if a potentially blocking operation is present directly within an entry_body or the body of a protected subprogram.
NOTES
11 An operation that causes a task to be blocked within a foreign language domain is not defined to be potentially blocking, and need not be detected.
