Strings

For information about functions that copy, concatenate, and format strings in a manner that prevents buffer overrun errors, see Safe String Functions. Other string manipulation functions include the following:

RtlInitString

Initializes the specified string in a buffer.

RtlInitAnsiString

Initializes the specified ANSI string in a buffer.

RtlInitUnicodeString

Initializes the specified Unicode string in a buffer.

RtlAnsiStringToUnicodeSize

Returns the size in bytes required to hold a Unicode version of a given buffered ANSI string.

RtlAnsiStringToUnicodeString

Converts a buffered ANSI string to a Unicode string, given a pointer to the source-string buffer and the address of caller-supplied storage for a pointer to the destination buffer. (This routine allocates a destination buffer if the caller does not supply the storage.) You can also use the string manipulation routines provided by a compiler to convert ANSI strings to Unicode.

RtlFreeUnicodeString

Releases a buffer containing a Unicode string, given a pointer to the buffer returned by RtlAnsiStringToUnicodeString.

RtlUnicodeStringToAnsiString

Converts a buffered Unicode string to an ANSI string, given a pointer to the source-string buffer and the address of caller-supplied storage for a pointer to the destination buffer. (This routine allocates a destination buffer if the caller does not supply the storage.)

RtlFreeAnsiString

Releases a buffer containing an ANSI string, given a pointer to the buffer returned by RtlUnicodeStringToAnsiString.

RtlAppendUnicodeStringToString

Concatenates a copy of a buffered Unicode string with a buffered Unicode string, given pointers to both buffers.

RtlAppendUnicodeToString

Concatenates a given input string with a buffered Unicode string, given a pointer to the buffer.

RtlCopyString

Copies the source string to the destination, given pointers to both buffers, or sets the length of the destination string (but not the length of the destination buffer) to zero if the optional pointer to the source-string buffer is NULL.

RtlCopyUnicodeString

Copies the source string to the destination, given pointers to both buffers, or sets the length of the destination string (but not the length of the destination buffer) to zero if the optional pointer to the source-string buffer is NULL.

RtlEqualString

Returns TRUE if the given ANSI alphabetic strings are equivalent.

RtlEqualUnicodeString

Returns TRUE if the given buffered strings are equivalent.

RtlCompareString

Compares two buffered, single-byte character strings and returns a signed value indicating whether they are equivalent or which is greater.

RtlCompareUnicodeString

Compares two buffered Unicode strings and returns a signed value indicating whether they are equivalent or which is greater.

RtlUpperString

Converts a copy of a buffered string to uppercase and stores the copy in a destination buffer.

RtlUpcaseUnicodeString

Converts a copy of a buffered Unicode string to uppercase and stores the copy in a destination buffer.

RtlIntegerToUnicodeString

Converts an unsigned integer value in the specified base to one or more Unicode characters in a buffer.

RtlUnicodeStringToInteger

RtlUnicodeStringToInteger converts the Unicode string representation of an integer into its integer equivalent.
