C Specification

To release a program object, call the function

// Provided by CL_VERSION_1_0
cl_int clReleaseProgram(
    cl_program program);

Parameters

  • program is the program object to be released.

Description

The program reference count is decremented. The program object is deleted after all kernel objects associated with program have been deleted and the program reference count becomes zero.

clReleaseProgram returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors:

  • CL_INVALID_PROGRAM if program is not a valid program 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.

Using this function to release a reference that was not obtained by creating the object or by calling clRetainProgram causes undefined behavior.
