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 2.2] void SafeRenderer::deallocFromMemoryPool(SafeRenderer::quint8 *memoryPtr)
Deallocates reserved memoryPtr from the memory pool.
This function is provided with a default empty implementation. Users who implement a custom allocAlignedFromMemoryPool() function with dynamic memory allocation may also want to customize this function to properly free allocated memory.
This function was introduced in QtSafeRenderer 2.2.
[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 filePath.
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.
[since QtSafeRenderer 2.2] SafeRenderer::quint16 SafeRenderer::qt_checksum_partial(const SafeRenderer::quchar *const dataPtr, const size_t dataLength, const SafeRenderer::quint16 currentCrc)
Calculates a partial CRC-16 checksum for the given data.
This function calculates a partial CRC-16 checksum for the data.
dataPtr Pointer to the data over which the CRC is calculated. dataLength The number of bytes in the data. currentCrc The current CRC value, which should be 0xFFFFU for the first call, or the result from a previous call to this function for subsequent calls.
Returns The updated CRC value. This CRC is not yet finalized; to finalize, the result must be complemented and masked as shown in qt_checksum.
Note: The checksum calculation is independent of byte order (endianness) and follows the ISO 3309 standard. This is a 16-bit cache conserving implementation using a 16-entry table.
Note: If dataPtr is NULL, the function returns 0.
Note: To finalize the CRC, complement the returned value and mask it with 0xFFFF (e.g., `~crc & 0xFFFFU`).
This function was introduced in QtSafeRenderer 2.2.
size_t SafeRenderer::safe_strlen(const qchar[] strArg, const size_t maxLength = Constraints::MAX_LEN_OF_TEXT)
Returns the length of the strArg c-style string, or maxLength if the string is not \0-terminated.
Note: This function is originated from https://www.misra.org.uk/forum/viewtopic.php?t=1160
void SafeRenderer::updateCRC(const quint8[4] colorVal, SafeRenderer::quint32 &crcArg)
Updates the CRC32 checksum based on a given colorVal.
colorVal an array of four bytes representing the color in ARGB format. crcArg a reference to an unsigned 32-bit integer where the computed CRC32 value will be stored.
Available under certain Qt licenses.
