Coprocessing Functions

Coprocess Identifiers

Coprocess identifiers are values of type coproc_t . They are returned by the costart function when a coprocess is created and passed to cocall to indicate the coprocess to be resumed. 0 is not a valid coprocess ID; this value is returned by costart when a new coprocess cannot be created.

Each coprocess has a unique ID value; the IDs of ended coprocesses are not reused.

The IDs of specific coprocesses can be found by calling the coproc function. See coproc for details.
