.SH DESCRIPTION
.sp
The fetch and increment routines retrieve the value at address
\fBtarget\fP on PE \fBpe\fP, and update \fBtarget\fP with the result of
incrementing the retrieved value by one. The operation must be completed
without the possibility of another process updating \fBtarget\fP between
the time of the fetch and the update.
.sp
The arguments are as follows:
.INDENT 0.0
.TP
.B target
The remotely accessible integer data object to be updated on the
remote PE. The type of target should match that implied in the
SYNOPSIS section.
.TP
.B pe
An integer that indicates the PE number upon which target is to be
updated. If you are using Fortran, it must be a default integer
value.
.UNINDENT
.SH NOTES
.sp
The term remotely accessible is defined in \fIintro_shmem\fP(3).
.SH RETURN VALUES
.sp
The contents that had been at the target address on the remote PE prior
to the increment.
