NAME
clGetKernelInfo - Returns information about the kernel object.
cl_int clGetKernelInfo(cl_kernel kernel, cl_kernel_info param_name,
size_t param_value_size, void *param_value,
size_t *param_value_size_ret);
PARAMETERS
kernel
Specifies the kernel object being queried.
param_name
Specifies the information to query. The list of supported param_name types and the
information returned in param_value by clGetKernelInfo is described in the table
below.
param_value
A pointer to memory where the appropriate result being queried is returned. If
param_value is NULL, it is ignored.
param_value_size
Used to specify the size in bytes of memory pointed to by param_value. This size must
be ≥ size of return type as described in the table below.
┌──────────────────────────┬─────────────┬─────────────────────────────┐
│cl_kernel_info │ Return Type │ Info. returned in │
│ │ │ param_value │
├──────────────────────────┼─────────────┼─────────────────────────────┤
│CL_KERNEL_FUNCTION_NAME │ char[] │ Return the kernel │
│ │ │ function name. │
├──────────────────────────┼─────────────┼─────────────────────────────┤
│CL_KERNEL_NUM_ARGS │ cl_uint │ Return the number of │
│ │ │ arguments to kernel. │
├──────────────────────────┼─────────────┼─────────────────────────────┤
│CL_KERNEL_REFERENCE_COUNT │ cl_uint │ Return the kernel │
│ │ │ reference count. │
│ │ │ │
├──────────────────────────┼─────────────┼─────────────────────────────┤
│CL_KERNEL_CONTEXT │ cl_context │ Return the context │
│ │ │ associated with kernel. │
├──────────────────────────┼─────────────┼─────────────────────────────┤
│CL_KERNEL_PROGRAM │ cl_program │ Return the program │
│ │ │ object associated with │
│ │ │ kernel. │
├──────────────────────────┼─────────────┼─────────────────────────────┤
│CL_KERNEL_ATTRIBUTES │ char[] │ Returns any attributes │
│ │ │ specified using the │
│ │ │ __attribute(3clc)__ │
│ │ │ qualifier with the │
│ │ │ kernel function │
│ │ │ declaration in the │
│ │ │ program source. These │
│ │ │ attributes include those │
│ │ │ on the │
│ │ │ __attribute(3clc)__ page │
│ │ │ and other attributes │
│ │ │ supported by an │
│ │ │ implementation. │
│ │ │ │
│ │ │ Attributes are returned │
│ │ │ as they were declared │
│ │ │ inside │
│ │ │ __attribute(3clc)__((...)), │
│ │ │ with any surrounding │
│ │ │ whitespace and embedded │
│ │ │ newlines removed. When │
│ │ │ multiple attributes are │
│ │ │ present, they are │
│ │ │ returned as a single, │
│ │ │ space delimited string. │
└──────────────────────────┴─────────────┴─────────────────────────────┘
param_value_size_ret
the actual size in bytes of data copied to param_value. If param_value_size_ret is
NULL, it is ignored.
ERRORS
Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of
the following errors:
• CL_INVALID_VALUE if param_name is not valid, or if size in bytes specified by
param_value_size is < size of return type as described in the table above and
param_value is not NULL.
• CL_INVALID_KERNEL if kernel is not a valid kernel object.
• CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL
implementation on the device.
• CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the
OpenCL implementation on the host.
