843 sigact
844 Contains an array of sigaction structures describing the current

847 that the action for signal number n appears in position n-1 of the

851 Contains the initial values of the process's aux vector in an array of

853 passed by the operating system as startup information to the dynamic
854 linker.

857 This file exists only on x86-based machines. It is non-empty only if
858 the process has established a local descriptor table (LDT). If non-
859 empty, the file contains the array of currently active LDT entries in
860 an array of elements of type struct ssd, defined in <sys/sysi86.h>, one
861 element for each active LDT entry.

2206
2207
2208 EAGAIN
2209 The traced process has performed an exec(2) of a
2210 setuid/setgid object file or of an object file that it
2303 elements out of order for descriptive clarity. The actual structure
2304 definitions are contained in <procfs.h>.
2305
2306 BUGS
2307 Because the old ioctl(2)-based version of /proc is currently supported
2308 for binary compatibility with old applications, the top-level directory
2309 for a process, /proc/pid, is not world-readable, but it is world-
2310 searchable. Thus, anyone can open /proc/pid/psinfo even though ls(1)
2311 applied to /proc/pid will fail for anyone but the owner or an
2312 appropriately privileged process. Support for the old ioctl(2)-based
2313 version of /proc will be dropped in a future release, at which time the
2314 top-level directory for a process will be made world-readable.
2315
2316
2317 On SPARC based machines, the types gregset_t and fpregset_t defined in
2318 <sys/regset.h> are similar to but not the same as the types prgregset_t
2319 and prfpregset_t defined in <procfs.h>.
