clCreateProgramWithSource

Creates a program object for a context, and loads the source code specified by the text strings in the strings array into the program object.

cl_program clCreateProgramWithSource(cl_context context,
                                     cl_uint count,
                                     const char **strings,
                                     const size_t *lengths,
                                     cl_int *errcode_ret)

Parameters

context

Must be a valid OpenCL context.

strings

An array of count pointers to optionally null-terminated character strings that make up the source code.

lengths

An array with the number of chars in each string (the string length). If an element in lengths is zero, its accompanying string is null-terminated. If lengths is NULL, all strings in the strings argument are considered null-terminated. Any length value passed in that is greater than zero excludes the null terminator in its count.

errcode_ret

Returns an appropriate error code. If errcode_ret is NULL, no error code is returned.

Description

This function creates a program object for a context, and loads the source code specified by the text strings in the strings array into the program object. The devices associated with the program object are the devices associated with context. The source code specified by strings is either an OpenCL C program source, header or implementation-defined source for custom devices that support an online compiler. OpenCL C++ is not supported as an online-compiled kernel language through this interface.

Errors

clCreateProgramWithSource returns a valid non-zero program object and errcode_ret is set to CL_SUCCESS if the program object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret:

  • CL_INVALID_CONTEXT if context is not a valid context.

  • CL_INVALID_VALUE if count is zero or if strings or any entry in strings is NULL.

  • 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.
