WebJun 17, 2024 · strncpy has two advantages over strcpy.First, if new_name doesn't fit in the buffer, there is no buffer overrun. Second, if new_name is smaller than the size of the buffer, all trailing bytes are set to 0, as stated in the documentation:. If the length of src is less than n, strncpy() writes additional null bytes to dest to ensure that a total of n bytes are written. WebJul 12, 2013 · To convert an int to 4 bytes, you do not need to go through hex : 2 solutions, 1) use your int as a byte array : C++. int value = 900 ; BYTE* pValue= (BYTE*)&value; //pValue [0], pValue [1], pValue [2] & pValue [3] will contain the 4 bytes. 2) use shift on your int in a loop : C++. int value = 900 ; int tmp= value ; for ( int i= 0 ;i <4 ;++i ...
