NAME

       clRetainMemObject - Increments the memory object reference count.

       cl_int clRetainMemObject(cl_mem memobj);

PARAMETERS

       memobj
           A valid memory object.

NOTES

       clCreateBuffer(3clc), clCreateSubBuffer(3clc), and clCreateImage(3clc), and perform an implicit retain.

       After the memobj reference count becomes zero and commands queued for execution on a command-queue(s)
       that use memobj have finished, the memory object is deleted. If memobj is a buffer object, memobj cannot
       be deleted until all sub-buffer objects associated with memobj are deleted.

ERRORS

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

       •   CL_INVALID_MEM_OBJECT if memobj is a not a valid memory object (buffer or image 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.

SPECIFICATION
