NAME¶
vstoren - Write sizeof bytes (gentypen) to memory.¶
void
vstoren(gentypen data,
size_t offset,
__global gentype *p);
void
vstoren(gentypen data,
size_t offset,
__local gentype *p);
void
vstoren(gentypen data,
size_t offset,
__private 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¶
Vector Data Load and Store Functions allow you to read and write vector types from a pointer to memory. 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. 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(3clc), local(3clc), or private(3clc) memory for store functions. The pointer argument p can be a pointer to __global, __local, constant(3clc) or __private memory for load functions. When extended by the cl_khr_fp16(3clc) extension, the generic type gentype n is extended to include half, half2, half3, half4, half8, and half16. vstore3, and vstore_half3 write x, y, z components from a 3-component vector to address ( p + ( offset * 3)).SPECIFICATION¶
