驱动程序可用的安全字符串函数表Windows Driver Kit: Kernel-Mode Driver Architecture Summary of Kernel-Mode Safe String Functions The following table summarizes the safe string functions that are available to kernel-mode drivers, and it indicates the C/C++ language runtime library functions that they replace. If a function's name contains Cb, the function treats strings as byte-counted. If a function's name contains Cch, the function treats strings as character-counted. Functions Purpose Replaces RtlStringCbCat RtlStringCbCatEx RtlStringCchCat RtlStringCchCatEx RtlUnicodeStringCat RtlUnicodeStringCatEx RtlUnicodeStringCatString RtlUnicodeStringCatStringEx RtlUnicodeStringCbCatStringN RtlUnicodeStringCbCatStringNEx RtlUnicodeStringCchCatStringN RtlUnicodeStringCchCatStringNEx Concatenate two strings. strcat wcscat RtlStringCbCatN RtlStringCbCatNEx RtlStringCchCatN RtlStringCchCatNEx RtlUnicodeStringCbCatN RtlUnicodeStringCbCatNEx RtlUnicodeStringCchCatN RtlUnicodeStringCchCatNEx Concatenate two byte-counted strings, while limiting the size of the appended string. strncat wcsncat RtlStringCbCopy RtlStringCbCopyEx RtlStringCbCopyUnicodeString RtlStringCbCopyUnicodeStringEx RtlStringCchCopy RtlStringCchCopyEx RtlStringCchCopyUnicodeString RtlStringCchCopyUnicodeStringEx RtlUnicodeStringCopy RtlUnicodeStringCopyEx RtlUnicodeStringCopyString RtlUnicodeStringCopyStringEx Copy a string into a buffer. strcpy wcscpy RtlStringCbCopyN RtlStringCbCopyNEx RtlStringCchCopyN RtlStringCchCopyNEx RtlUnicodeStringCbCopyN RtlUnicodeStringCbCopyNEx RtlUnicodeStringCchCopyN RtlUnicodeStringCchCopyNEx RtlUnicodeStringCbCopyStringN RtlUnicodeStringCbCopyStringNEx RtlUnicodeStringCchCopyStringN RtlUnicodeStringCchCopyStringNEx Copy a string into a buffer, while limiting the size of the copied string. strncpy wcsncpy RtlStringCbLength RtlStringCchLength RtlUnalignedStringCbLength RtlUnalignedStringCchLength Determine the length of a supplied string. strlen wcslen RtlStringCbPrintf RtlStringCbPrintfEx RtlStringCchPrintf RtlStringCchPrintfEx RtlUnicodeStringPrintf RtlUnicodeStringPrintfEx Create a formatted text string that is based on a format string and a set of additional function arguments. sprintf swprintf _snprintf _snwprintf RtlStringCbVPrintf RtlStringCbVPrintfEx RtlStringCchVPrintf RtlStringCchVPrintfEx RtlUnicodeStringVPrintf RtlUnicodeStringVPrintfEx Create a formatted text string that is based on a format string and one additional function argument. vsprintf vswprintf _vsnprintf _vsnwprintf RtlUnicodeStringInit RtlUnicodeStringInitEx RtlUnicodeStringValidate RtlUnicodeStringValidateEx Initialize or validate a UNICODE_STRING structure.
