/**
 * _printf - A custom implementation of the printf function.
 *
 * @format: The format string that specifies how subsequent arguments are
 * converted for output.
 *
 * This function takes a format string and a variable number of arguments,
 * initializes an arg_data_t struct and an array of specifier_t structs, and
 * processes the format string. If the format string is NULL, it returns -1.
 * It uses the process_format_string function to process the format string and
 * update the count of printed characters in the arg_data_t struct.If the count
 * is -1 after processing the format string, it returns -1. Otherwise, it ends
 * the va_list in the arg_data_t struct and returns the count of printed
 * characters.
 *
 * Return: The total count of printed characters if the format string is
 * processed successfully, -1 otherwise.
