Protothreads: lightweight, stackless threads in C. Protothreads are extremely lightweight stackless threads designed for severely memory constrained systems such as small embedded systems or sensor network nodes. Protothreads provide linear code execution for event-driven systems implemented in C. Protothreads can be used with or without an underlying operating system. Main features: No machine specific code - the protothreads library is pure C Does not use error-prone functions such as longjmp() Very small RAM overhead - only two bytes per protothread Can be used with or without an OS Provides blocking wait without full multi-threading or stack-switching Freely available under a BSD-like open source license 4:11:48 PM
