Provides some internal, more performant, but unsafe helper functions for the ZyanString
data-type.
Most of these functions are very similar to the ones in Zycore/String.h
, but inlined and without optional overhead like parameter-validation checks, etc ...
The ZyanString
data-type is able to dynamically allocate memory on the heap, but as Zydis
is designed to be a non-'malloc'ing library, all functions in this file assume that the instances they are operating on are created with a user-defined static-buffer.
#define ZYDIS_STRING_ASSERT_NULLTERMINATION | ( | string | ) | ZYAN_ASSERT(*(char*)((ZyanU8*)(string)->vector.data + (string)->vector.size - 1) == '\0'); |

#define ZYDIS_STRING_NULLTERMINATE | ( | string | ) | *(char*)((ZyanU8*)(string)->vector.data + (string)->vector.size - 1) = '\0'; |
Writes a terminating '\0' character at the end of the string data.
