int uremove(char *s, int index);
DESCRIPTIONRemoves the character at the specified `index' within the string, sliding the rest of the data back to fill the gap. If `index' is negative, it counts backward from the end of the string. Example:
int length_in_bytes = ustrsizez(text_string); ... length_in_bytes -= uremove(text_string, -1);
RETURN VALUEReturns the number of bytes by which the trailing part of the string was moved.
