Function Documentation
SafeRenderer::quint32 SafeRenderer::ARGBtoInt(const SafeRenderer::ARGB &color)
Cast color ARGB to Int.
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.
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.
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.
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.
size_t SafeRenderer::safe_strlen(const SafeRenderer::qchar *const strArg)
Returns the length of the strArg c-style string.
Note: This function is originated from https://www.misra.org.uk/forum/viewtopic.php?t=1160
