\fI\%shmem_long_inc\fP(3), \fI\%shmem_longlong_inc\fP(3) \- These routines
perform an atomic increment operation on a remote data object.
.SH SYNOPSIS

.SH DESCRIPTION
.sp
The atomic increment routines replace the value of \fBtarget\fP with its
value incremented 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
None.
