Detailed Description

String and array transposition functions.

This header provides functions to convert between different representations of integer arrays and strings. It includes functions for converting:

• 32-bit integers in big-endian format to native 32-bit integers.
• Hexadecimal strings to binary arrays.
• Native 32-bit integers to byte arrays in big-endian format.
• 8-bit character arrays to zero-padded 32-bit scalar integers.

// Example: Convert a hexadecimal string to a binary array.
const char* hex_str = "1a2b3c4d";
uint8_t binary[4];
qsc_transpose_hex_to_bin(binary, hex_str, 8);
