Function Documentation

SafeRenderer::quint32 SafeRenderer::ARGBtoInt(const SafeRenderer::ARGB &color)

Cast color ARGB to Int.

[since QtSafeRenderer 1.2] SafeRenderer::quint8 *SafeRenderer::allocAlignedFromMemoryPool(const SafeRenderer::quint32 sizeArgInBytes)

Reserves a buffer with size sizeArgInBytes. The index to the buffer is adjusted so that the underlying address in memory is aligned to 4 byte boundary for safe access via quint32 pointer. Returns pointer to the reserved buffer.

This function was introduced in QtSafeRenderer 1.2.

[since QtSafeRenderer 1.0] SafeRenderer::quint32 SafeRenderer::qsafe_hash(const SafeRenderer::qchar *const dataPtr, const size_t dataLength)

Calculates the hash value of the string.

This is a copy of the implementation of the Qt 4 qHash algorithm. dataPtr is the pointer to the source string. dataLength is the length of the string.

This function was introduced in QtSafeRenderer 1.0.

[since QtSafeRenderer 2.0] SafeRenderer::quint32 SafeRenderer::qsafe_hash_string(const SafeRenderer::qchar *const dataPtr)

Calculates the hash value of the null-terminated string.

dataPtr is the pointer to the source string.

This function was introduced in QtSafeRenderer 2.0.

[since QtSafeRenderer 1.0] SafeRenderer::quint16 SafeRenderer::qt_checksum(const SafeRenderer::quchar *const dataPtr, const size_t dataLength)

Returns the CRC-16 checksum of the first dataLength bytes starting at dataPtr.

Note: The checksum is independent of the byte order (endianness) and will be calculated according to the algorithm published in the ISO 3309 standard.

Note: This function is a 16-bit cache conserving (16 entry table) implementation of the CRC-16-CCITT algorithm.

Note: If data pointer is NULL a 0 is returned.

This function was introduced in QtSafeRenderer 1.0.

[since QtSafeRenderer 2.1] SafeRenderer::quint16 SafeRenderer::qt_checksum_file(const SafeRenderer::qchar *const filePath)

Returns the CRC-16 checksum of a file contents given filename .

Note: The checksum is independent of the byte order (endianness) and will be calculated according to the algorithm published in the ISO 3309 standard.

Note: This function is a 16-bit cache conserving (16 entry table) implementation of the CRC-16-CCITT algorithm.

This function was introduced in QtSafeRenderer 2.1.

size_t SafeRenderer::safe_strlen(const SafeRenderer::qchar [] strArg, const size_t maxLength = Constraints::MAX_LEN_OF_TEXT)

Returns the length of the strArg c-style string.
