pub unsafe extern "C" fn GC_set_markers_count(arg1: c_uint)Expand description
Set the number of marker threads (including the initiating one)
to the desired value at start-up. Zero value means the collector
is to decide. If the correct nonzero value is passed, then
GC_parallel will be set to the value minus one later. Has no effect
if called after the collector initialization. Does not itself cause
creation of the marker threads. Does not use any synchronization.
