SYNOPSIS

#include <coproc.h>

void coexit(void *val);

DESCRIPTION

coexit terminates execution of the current coprocess and returns a pointer value to its cocaller. The call to cocall that called the terminating coprocess is resumed, and it returns the value specified by val .

If coexit is called by the main coprocess, it is treated as a call If coexit is called by the main coprocess, it is treated as a call to exit. Specifically, coexit(val) is treated as exit(val? *(int *) val: 0) .

coexit is implemented as a longjmp to a location within the library coprocess initialization routine. This means that the blkjmp function can be used within a coprocess to intercept calls to coexit .

If program execution is terminated by a call to the exit function If program execution is terminated by a call to the exit function while there are still coprocesses active, each active coprocess is terminated by an implicit call to coexit . These calls also can be intercepted by blkjmp ; however, note that in this context any use of coreturn fails, because no calling coprocess is defined.

RETURN VALUE

Control does not return from coexit .

EXAMPLE

See the example for coreturn .
