STORAGE-CLASS QUALI(3clc) | OpenCL Manual | STORAGE-CLASS QUALI(3clc) |
NAME¶
Storage-class_Qualifiers - The typedef, extern and static storage-class specifiers.
NOTES¶
The typedef, extern, and static storage-class specifiers are supported. The auto and register storage-class specifiers are not supported..
The extern storage-class specifier can only be used for functions (kernel and non-kernel functions) and global variables declared in program scope. The static storage-class specifier can only be used for non-kernel functions and global variables declared in program scope.
Example¶
extern constant float4 noise_table[256]; static constant float4 color_table[256]; extern kernel void my_foo(image2d_t img); extern void my_bar(global float *a); kernel void my_func(image2d_t img, global float *a) { extern constant float4 a; // error. static constant float4 b; // error. static float c; // error. ... my_foo(img); ... my_bar(a); ... } |
