The memcpy() function copies the entire struct layout to a buffer. You have to pass a pointer to the struct as the source argument, the buffer as the destination argument, and the size of the struct. If the struct in your code has pointers, handle them separately. Implementation C #inclu...
The memcpy_s function returns zero if there was no runtime-constraint violation. Otherwise, a nonzero value is returned. Example program to describe how to use memcpy_s C: The following program illustrates the working of the memcpy_s() function in the C language. #define __STDC_WANT_LIB_...
copy_kprobe Keep all fields in the kprobe consistent kdb_read kdb_read* This function reads a string of characters, terminated by* a newline, or by reaching the end of the supplied buffer,* from the current kernel debugger console device.* Parameters:* Returns:* Returns a pointer to the ...
Knowing Microsoft, the actual function is hidden behind several defines and the one you get will depend on your settings. Nov 29, 2011 at 1:58am helios (17607) Yes, but have you ever seen a naive memcpy()? memcpy() is, in any usable implementation, the fastest method to copy non...
I think the benchmark has changed between when I tested (and the memcpy function has quite a bit too) - I'll re-check. Unless I'm missing something, I would be biased to keep the aligned strategy until/unless we diverge implementation based on whether a target has slow unaligned access...
The memcpy() function shall copy n bytes from the object pointed to by s2 into the object pointed to by s1. If copying takes place between objects that overlap,

The problem is that when we call the function "assign" with s1 equal to s2, gcc generates a call to memcpy with overlapping arguments and that violates the C standard. Note that if the memcpy implementation uses an instruction such as "DC ZVA" to ...
