Function Documentation

◆ dirname_alloc()

char * dirname_alloc ( const char * path )

Return the directory part of path in a (new allocated) string.

Definition at line 127 of file example.c.

◆ error_name()

std::string error_name ( cl_int code )

Return the error name corresponding to the error code.

Definition at line 167 of file example.c.

◆ file_to_alloc_string()

char * file_to_alloc_string ( const char * filename )

Read the file and return its content to a (new allocated) string. If failed then print a error message and exit.

Definition at line 179 of file example.c.

◆ get_device_id()

cl_device_id get_device_id	(	unsigned int	platform_i,
		unsigned int	device_i
	)

Return the given id device of the given platform OpenCL, or exit if doesn't exists.

Parameters

platform_i
device_i

Returns: OpenCL device id

Definition at line 209 of file example.c.

◆ get_device_info_alloc_string()

char * get_device_info_alloc_string	(	cl_device_id	device_id,
		cl_device_info	param_name
	)

Return a (new allocated) string corresponding to device info parameter.

Definition at line 255 of file example.c.

◆ main()

int main	(	int	argc,
		const char *const	argv[]
	)

Get the optional parameter –device platform:device and run the kernel ../kernel/example.cl.

Definition at line 486 of file example.c.

◆ print_error()

void print_error	(	cl_int	code,
		const char *	message
	)

If code != 0 then print an error message corresponding to the error code.

Definition at line 274 of file example.c.

◆ run_example()

void run_example	(	unsigned int	nb_work_group,
		unsigned int	nb_work_items_by_work_group,
		cl_device_id	device_id,
		bool	debug,
		const char *	path
	)

Run the kernel ../kernel/example.cl.

If debug then run the kernel in debug mode, else run the kernel with the macro NDEBUG defined.

Definition at line 288 of file example.c.

Variable Documentation

◆ errors_map

const error_name_t errors_map[61]

List of all error codes and names extracted from /usr/include/CL/cl.h.

Definition at line 43 of file example.c.

◆ errors_map_size

const unsigned int errors_map_size = 61

Number of elements in errors_map.

Definition at line 51 of file example.c.
