The OpenCL language, which extends C99, does not provide the memcpy fu开发者_如何学JAVAnction. What should be used instead?As far as I know, there is nothing like that defined in OpenCL. OpenCL does n
When I was reading the nginx code, I have seen this function : #define ngx_cpymem(dst, src, n)(((u_char *) memcpy(dst, src, n)) + (n))
I am confuse on how to read the pointers copied in an array using memcpy. Following is what I have tried, but does not work.
EDIT: I\'m sorry for my mistakes in my code snippets, now I see both outputs were same. Below is an edited version.
As pointed out in an answer to this question, the compiler (in this case gcc-4.1.2, yes it\'s old, no I can\'t change it) can replace struct assignments with memcpy where it thinks it is appropriate.
I call some C++ functions inside a signal hand开发者_开发知识库ler and my program is terminated by segmentation fault.
Is this ok? char buf[] = { 0, 1, 2 }; memcpy(b开发者_Python百科uf, buf + 1, 2); Does having a bigger datatype make any difference? I know I could use memmove(), but I\'m just curious.The effects of
