Pclearfault,
Lclearfault — clear process
and thread faults
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
Pclearfault(struct ps_prochandle
*P);
int
Lclearfault(struct ps_lwphandle
*L);
During normal operation a process may encounter a fault, due to a hardware exception, identifying a problem with the running process. Hardware faults include things like executing illegal instructions, encountering a breakpoint, and arithmetic exceptions. Faults are discussed further in proc(5).
The
Pclearfault()
function instructs the system to clear any fault pending delivery to a
thread in the process represented by the process handle
P. The pending fault will never be delivered to
process represented by P.
The
Lclearfault()
function is identical to the Pclearfault() function,
except rather than operating on the representative thread of the process it
operates on the thread handle L.
The
Pclearfault()
and Lclearfault() functions only have meaning for
active processes. They will fail on process handles corresponding to zombie
processes, ELF objects, and cores.
Upon successful completion, the
Pclearfault() and
Lclearfault() functions clear pending faults and
return 0.
Otherwise, -1 is
returned,
errno is
set to indicate the error, and no faults are cleared.
For a full list of possible errors see the DIAGNOSTICS section in proc(5).
See LOCKING in libproc(3LIB).
