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:

These functions decode signal-specific signal codes stored in the si_code field of the siginfo_t object associated with an instance of signal:

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.
