sysdecode_kevent(3) FreeBSD Library Functions Manual sysdecode_kevent(3) NAME sysdecode_kevent, sysdecode_kevent_fflags, sysdecode_kevent_filter, sysdecode_kevent_flags - output description of kevent structure fields LIBRARY System Argument Decoding Library (libsysdecode, -lsysdecode) SYNOPSIS #include <sysdecode.h> void sysdecode_kevent_fflags(FILE *fp, short filter, int fflags, int base); bool sysdecode_kevent_flags(FILE *fp, int flags, int *rem); const char * sysdecode_kevent_filter(int filter); DESCRIPTION These functions provide text descriptions of struct kevent fields. The sysdecode_kevent_fflags() function outputs a text description of the fflags member of a struct kevent to the stream fp. For the EVFILT_READ, EVFILT_WRITE, EVFILT_VNODE, EVFILT_PROC, EVFILT_PROCDESC, EVFILT_TIMER, and EVFILT_USER filters, sysdecode_kevent_fflags() outputs a bitmask of filter-specific NOTE_* flags as documented in kevent(2). For other values of filter, the value of fflags is output in the indicated base (one of 8, 10, or 16). The sysdecode_kevent_filter() function returns a text description of the filter member of a struct kevent. NULL is returned if the filter value is unknown. The sysdecode_kevent_flags() function outputs a text description of the flags member of a struct kevent to the stream fp. This function uses the same calling convention and formatting as the other functions described in sysdecode_mask(3). RETURN VALUES The sysdecode_kevent_filter function returns the name of a filter or NULL if the filter value is unknown. The sysdecode_kevent_flags function returns true if any flags in the flags field were decoded and false if no flags were decoded.
