Detailed Description

Local continuations form the basis for implementing protothreads. A local continuation can be set in a specific function to capture the state of the function. After a local continuation has been set can be resumed in order to restore the state of the function at the point where the local continuation was set.

 if(s != NULL) { \
 goto *s; \
 } \
 } while(0)

#define LC_SET ( s )

Value:
