Others, Allocate successfully and return the initial address pointer of the memory block. Example usage: #include "CCRTOS.h" void TaskN (void *pdata) { unsigned int *ptr; ... /* Allocate 20 words of memory block from kernel heap */ ptr = (unsigned int *)CoKmalloc(20*4); /* process ptr here */ ... /* Release memory block to kernel heap */ CoKfree(ptr); ... } Note: Once you called CoKmalloc(), it will cost 8 bytes to manage this memory block. 69
