AIX: Finding processes attached to shared memory

Is there some way to tell what processes are attached to a shared memory segment?

Neither the creator's pid nor last...

NAME

       memccpy, memchr, memcmp, memcpy, memmove, memset - memory operations

SYNOPSIS

       #include <u.h>
       #include <libc.h>

       void* memccpy(void *s1, void *s2, int c, long n)

       void* memchr(void *s, int c, long n)

       int   memcmp(void *s1, void *s2, long n)

       void* memcpy(void *s1, void *s2, long n)

       void* memmove(void *s1, void *s2, long n)

       void* memset(void *s, int c, long n)

DESCRIPTION

       These functions operate efficiently on memory areas (arrays of bytes bounded by a count, not terminated by a zero byte).  They do not check
       for the overflow of any receiving memory area.

       Memccpy copies bytes from memory area s2 into s1, stopping after the first occurrence of byte c has been copied, or after n bytes have been
       copied, whichever comes first.  It returns a pointer to the byte after the copy of c in s1, or zero if c was not found in the first n bytes
       of s2.

       Memchr returns a pointer to the first occurrence of byte c in the first n bytes of memory area s, or zero if c does not occur.

       Memcmp compares its arguments, looking at the first n bytes only, and returns an integer less than, equal to, or greater than 0,  according
       as s1 is lexicographically less than, equal to, or greater than s2.  The comparison is bytewise unsigned.

       Memcpy copies n bytes from memory area s2 to s1.  It returns s1.

       Memmove works like memcpy, except that it is guaranteed to work if s1 and s2 overlap.

       Memset sets the first n bytes in memory area s to the value of byte c.  It returns s.

SOURCE

       All  these  routines have portable C implementations in /sys/src/libc/port.  Most also have machine-dependent assembly language implementa-
       tions in /sys/src/libc/$objtype.

SEE ALSO

       strcat(2)

BUGS

       ANSI C does not require memcpy to handle overlapping source and destination; on Plan 9, it does, so memmove and memcpy behave identically.

       If memcpy and memmove are handed a negative count, they abort.
