DESCRIPTION Routine zx25callacc is used to confirm (accept) an inbound X.25 call.
The caller of this routine is responsible for performing any required
facilities and D-bit negotiation.

the calling program by giving the “-lzx25 -lzcom_c -lpthread” options to
cc(1) or ld(1).
Threads
Considerations
This routine may be called from a multi-threaded application using the
POSIX (1003.1c) kernel threads API package. It has the following
characteristics when called by multi-threaded applications:
cancellation point Thread cancellation can occur when a
thread calls this routine.
async-cancel unsafe The calling thread’s cancelability
type must be
PTHREAD_CANCEL_DEFERRED if
cancellation is enabled.
async-signal unsafe It cannot be called from a signal
handler.
fork unsafe It cannot be called by a child process
after fork(2) but before exec(2).
