DESCRIPTION
The sysdecode_enum functions return a text description of an integer
value. The text description matches the name of a C macro with the same
value as the sole function argument. NULL is returned if there is no
matching C macro name.
Most of these functions decode an argument passed to a system call:
Function System Call Argument
sysdecode_acltype() acl_get_file(3) type
sysdecode_atfd() openat(2) fd
sysdecode_extattrnamespace() extattr_get_fd(2) attrnamespace
sysdecode_fadvice() posix_fadvise(2) advice
sysdecode_fcntl_cmd() fcntl(2) cmd
sysdecode_getfsstat_mode() getfsstat(2) mode
sysdecode_idtype() procctl(2), waitid(2) idtype
sysdecode_itimer() getitimer(2), setitimer(2) which
sysdecode_kldsym_cmd() kldsym(2) cmd
sysdecode_kldunload_flags() kldunloadf(2) flags
sysdecode_lio_listio_mode() lio_listio(2) mode
sysdecode_madvice() madvise(2) advice
sysdecode_minherit_inherit() minherit(2) inherit
sysdecode_msgctl_cmd() msgctl(2) cmd
sysdecode_nfssvc_flags() nfssvc(2) flags
sysdecode_pathconf_name() pathconf(2) name
sysdecode_prio_which() getpriority(2) which
sysdecode_procctl_cmd() procctl(2) cmd
sysdecode_ptrace_request() ptrace(2) request
sysdecode_rlimit() getrlimit(2) resource
sysdecode_rtprio_function() rtprio(2) function
sysdecode_getrusage_who() getrusage(2) who
sysdecode_scheduler_policy() sched_setscheduler(2) policy
sysdecode_whence() lseek(2) whence
These functions decode signal-specific signal codes stored in the si_code
field of the siginfo_t object associated with an instance of signal:
Function Signal
sysdecode_sigbus_code() SIGBUS
sysdecode_sigchld_code() SIGCHLD
sysdecode_sigfpe_code() SIGFPE
sysdecode_sigill_code() SIGILL
sysdecode_sigsegv_code() SIGSEGV
sysdecode_sigtrap_code() SIGTRAP
Other functions decode the values described below:
sysdecode_ipproto() An IP protocol.
sysdecode_sctp_pr_policy() A PR-SCTP policy.
sysdecode_signal() A process signal.
sysdecode_sockaddr_family() A socket address family.
sysdecode_socketdomain() A socket domain.
sysdecode_vmresult() The return value of a function in the
virtual memory subsystem of the kernel
indicating the status of the associated
request.
RETURN VALUES
The sysdecode_enum functions return the name of a matching C macro or
NULL if no matching C macro was found.
