Function Documentation
◆ varint_read()
| int varint_read | ( | const uint8_t * | in, |
| size_t | in_len, | ||
| uint64_t * | value | ||
| ) |
Read Bitcoin-like varint from byte buffer.
- Parameters
-
[in] in Pointer to input byte buffer. [in] in_len Length of the input byte buffer. [out] value Pointer to 64-bit unsigned integer to output varint.
- Returns
- number of bytes read (1, 3, 5 or 9 bytes), -1 otherwise.
◆ varint_size()
| uint8_t varint_size | ( | uint64_t | value | ) |
Size of value represented as Bitcoin-like varint.
- Parameters
-
[in] value 64-bit unsigned integer to compute varint size.
- Returns
- number of bytes to write value as varint (1, 3, 5 or 9 bytes).
◆ varint_write()
| int varint_write | ( | uint8_t * | out, |
| size_t | offset, | ||
| uint64_t | value | ||
| ) |
Write Bitcoin-like varint to byte buffer.
- Parameters
-
[out] out Pointer to output byte buffer. [in] offset Offset in the output byte buffer. [in] value 64-bit unsigned integer to write as varint.
- Returns
- number of bytes written (1, 3, 5 or 9 bytes), -1 otherwise.
