Definition

int64_t trace (
    uint32_t mread_ptr,
    uint32_t mread_len,
    uint32_t dread_ptr,
    uint32_t dread_len,
    uint32_t as_hex
);

function trace(
    message: string | null,
    data: any,
    hex: boolean | 0 | 1
  ): ErrorCode

Example

#define SBUF(str) (uint32_t)(str), sizeof(str)
trace(SBUF("Buffer conatained"), SBUF(some_buffer), 1);
trace("Buffer conatained", some_buffer, 1);

Parameters
