pub unsafe extern "C" fn GC_set_handle_fork(arg1: c_int)Expand description
Overrides the default handle-fork mode. A nonzero value means GC
should install proper pthread_atfork handlers. Has effect only
if called before the collector initialization. Clients should call
GC_set_handle_fork() with nonzero argument if going to use fork
with the GC functions called in the child process. (Note that such
client and at-fork handler activities are not fully POSIX-compliant.)
GC_set_handle_fork() instructs GC_init to setup GC fork handlers
using pthread_atfork(), the latter might fail (or, even, absent on
some targets) causing abort at the collector initialization.
Issues with missing (or failed) pthread_atfork() could be avoided
by invocation of GC_set_handle_fork(-1) at application start-up and
surrounding each fork() with the relevant
GC_atfork_prepare/GC_atfork_parent/GC_atfork_child calls.
