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_semctl_cmd()semctl(2)cmd
sysdecode_shmctl_cmd()shmctl(2)cmd
sysdecode_shutdown_how()shutdown(2)how
sysdecode_sigprocmask_how()sigprocmask(2)how
sysdecode_sockopt_level()getsockopt(2)level
sysdecode_sysarch_number()sysarch(2)number
sysdecode_umtx_op()_umtx_op(2)op
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.
