Write sizeof bytes (gentypen) to memory.

void vstore n(gentype n data,
              size_t offset,
              gentype *p)

Description

Write sizeof(gentypen) bytes given by data to address (p + (offset * n)). The address computed as (p + (offset * n)) must be 8-bit aligned if gentype is char or uchar; 16-bit aligned if gentype is short, ushort, or half; 32-bit aligned if gentype is int, uint, or float; 64-bit aligned if gentype is long or ulong.

Notes

The generic type gentype is used to indicate the built-in data types char, uchar, short, ushort, int, uint, long, ulong, float, or double.

The generic type name gentypen represents n-element vectors of gentype elements. The suffix n is also used in the function names (i.e. vloadn, vstoren, etc.), where n = 2, 3, 4, 8, or 16.

Vector Data Load and Store Functions allow you to read and write vector types from a pointer to memory.

The suffix n in the function names (i.e. vload`n`, vstore`n` etc.) represent n-element vectors, where n = 2, 3, 4, 8 or 16.

The results of vector data load and store functions are undefined if the address being read from or written to is not correctly aligned. The pointer argument p can be a pointer to global, local, or private memory for store functions. The pointer argument p can be a pointer to global, local, constant or private memory for load functions.

Note
The vector data load and store functions variants that take pointer arguments which point to the generic address space are also supported.

When extended by the cl_khr_fp16 extension, the generic type gentypen is extended to include half, half2, half3, half4, half8, and half16.

When the half extension is enabled, the address computed as (p + (offset * n)) must be 16-bit aligned.

vstore3, and vstore_half3 write x, y, z components from a 3-component vector to address (p + (offset * 3)).
