HdfSbufWriteUint16 (struct HdfSBuf sbuf, uint16_t value) bool Writes a 16-bit unsigned integer to a SBuf.
HdfSbufWriteUint8 (struct HdfSBuf sbuf, uint8_t value) bool Writes an 8-bit unsigned integer to a SBuf.
HdfSbufWriteInt64 (struct HdfSBuf sbuf, int64_t value) bool Writes a 64-bit signed integer to a SBuf.
HdfSbufWriteInt32 (struct HdfSBuf sbuf, int32_t value) bool Writes a 32-bit signed integer to a SBuf.
HdfSbufWriteInt16 (struct HdfSBuf sbuf, int16_t value) bool Writes a 16-bit signed integer to a SBuf.
HdfSbufWriteInt8 (struct HdfSBuf sbuf, int8_t value) bool Writes an 8-bit signed integer to a SBuf.
HdfSbufWriteString (struct HdfSBuf sbuf, const char value) bool Writes a string to a SBuf.
HdfSbufReadBuffer (struct HdfSBuf sbuf, const void **data, uint32_t readSize) bool Reads a data segment from a SBuf.
HdfSbufReadUint64 (struct HdfSBuf sbuf, uint64_t value) bool Reads a 64-bit unsigned integer from a SBuf.
HdfSbufReadUint32 (struct HdfSBuf sbuf, uint32_t value) bool Reads a 32-bit unsigned integer from a SBuf.
HdfSbufReadUint16 (struct HdfSBuf sbuf, uint16_t value) bool Reads a 16-bit unsigned integer from a SBuf.
HdfSbufReadUint8 (struct HdfSBuf sbuf, uint8_t value) bool Reads an 8-bit unsigned integer from a SBuf.
HdfSbufReadInt64 (struct HdfSBuf sbuf, int64_t value) bool Reads a 64-bit signed integer from a SBuf.
HdfSbufReadInt32 (struct HdfSBuf sbuf, int32_t value) bool Reads a 32-bit signed integer from a SBuf.
HdfSbufReadInt16 (struct HdfSBuf sbuf, int16_t value) bool Reads a 16-bit signed integer from a SBuf.
HdfSbufReadInt8 (struct HdfSBuf sbuf, int8_t value) bool Reads an 8-bit signed integer from a SBuf.
HdfSbufReadString (struct HdfSBuf sbuf) const char Reads a string from a SBuf.
HdfSbufGetData (const struct HdfSBuf sbuf) uint8_t Obtains the pointer to the data stored in aSBuf.
HdfSbufFlush (struct HdfSBuf sbuf) void Clears the data stored in a SBuf.
HdfSbufGetCapacity (const struct HdfSBuf sbuf) size_t Obtains the capacity of a SBuf.
HdfSbufGetDataSize (const struct HdfSBuf sbuf) size_t Obtains the size of the data stored in a SBuf.
HdfSBufObtain (size_t capacity) struct HdfSBuf Obtains a SBuf instance.
HdfSBufObtainDefaultSize (void) struct HdfSBuf Obtains a SBuf instance of the default capacity (256 bytes).
HdfSBufBind (uintptr_t base, size_t size) struct HdfSBuf Creates a SBuf instance with the specified data and size. The pointer to the data stored in the SBuf is released by the caller, and the written data size should not exceed the specified value of size.
HdfSBufRecycle (struct HdfSBuf sbuf) void Releases a SBuf .
HdfSBufMove (struct HdfSBuf sbuf) struct HdfSBuf Creates a SBuf instance with an original SBuf. This function moves the data stored in the original SBuf to the new one without memory copy.
HdfSBufCopy (const struct HdfSBuf sbuf) struct HdfSBuf Creates a SBuf instance with an original SBuf. This function copies the data stored in the original SBuf to the new one.
HdfSbufTransDataOwnership (struct HdfSBuf sbuf) void Transfers the data ownership to a SBuf. Once the SBuf is released, the bound data memory is also released. This function is used together with HdfSBufBind.
