# shmem\_longdouble\_p.openmpi(3)

[*shmem\_char\_p*(3)](/shmem_char_p/3.md), [*shmem\_float\_p*(3)](/shmem_float_p/3.md), [*shmem\_int\_p*(3)](/shmem_int_p/3.md), [*shmem\_long\_p*(3)](/shmem_long_p/3.md), [*shmem\_short\_p*(3)](/shmem_short_p/3.md), [*shmem\_longlong\_p*(3)](/shmem_longlong_p/3.md), [*shmem\_longdouble\_p*(3)](/shmem_longdouble_p/3.md) - These routines provide a low latency mechanism to write basic types (char, short, int, float, double, long, long long, long double) to symmetric data objects on remote PEs.

## SYNOPSIS

C or C++:

```
#include <mpp/shmem.h>
void shmem_char_p(char *addr, char value, int pe)
void shmem_short_p(short *addr, short value, int pe)
void shmem_int_p(int *addr, int value, int pe)
void shmem_long_p(long *addr, long value, int pe)
void shmem_longlong_p(long long *addr, long long value, int pe)
void shmem_float_p(float *addr, float value, int pe)
void shmem_double_p(double *addr, double value, int pe)
void shmem_longdouble_p(long double *addr, long double value, int pe)
```

## DESCRIPTION

These routines provide a very low latency put capability for single elements of most basic types.

The arguments are as follows:

- **addr**

  The remotely accessible array element or scalar data object which will receive the data on the remote PE.

- **value**

  The value to be transferred to addr on the remote PE.

- **pe**

  The number of the remote PE.

As with shmem\_put(3), these functions start the remote transfer and may return before the data is delivered to the remote PE. Use [*shmem\_quiet*(3)](/shmem_quiet/3.md) to force completion of all remote PUT transfers.
