/*
Function: str_num_copy
Copies first num characters of a string to another.
Function: str_truncate
Truncates a string to a given length.
Parameters:
dst - Pointer to a buffer that shall receive the string.
src - String to be copied.
num - Number of characters to copy.
dst_size - Size of the buffer dst.
str - String to be truncated.
truncation_len - Maximum length of the returned string (not
counting the zero termination).
Remarks:
- The strings are treated as zero-terminated strings.
- Guarantees that dst string will contain zero-termination.
