Return to kdump_subr.h CVS log

Up to [local] / src / usr.bin / kdump

Convert syscall argument handling from a giant switch to a giant table.
While at it, use formatters for fds, counts, ids of all types, and "small
buffer sizes" that always show them in decimal, while paths, pointers, and
"big buffer sizes" get formatters that always show them in hex.  The -d
option only affects args when the -n option is used or for unknown syscalls,
as well as syscall return values, and unrecognized ioctls.
