Convert ASCII representation of a base 10 number to int64. This is needed as sscanf("%lld") or atoll() are not universally available.
- Parameters
-
| value | optionally zero terminated string containing a zero or one sign char ('+' or '-') and a number in base 10 chars, ie. "0..9" |
| length | chars to convert, must be more or equal than the chars before zero. This is useful for extracting values from non-zero terminated strings. |
| conversion_result | result of conversion |
- Returns
- will be set to true if at least one digit is found and a false is returned if: a) no digits found, ie. string is empty b) a non-digit or non-'+' or non-'-' char is found. c) more than one +, - chars are found
Note: the handling of a number with digits in front and non-digits at end (eg. "0zero") differs from sscanf(), as sscanf will return what it got converted and a success value even if the string ended with junk.
| void m2m::String::reserve |
( |
size_type |
n | ) |
|
Reserve internal string memory so that n characters can be put into the string (plus 1 for the NULL char). If there is already enough memory, nothing happens, if not, the memory is realloated to exactly this amount.
| void m2m::String::resize |
( |
size_type |
n | ) |
|
Resize string. If n is less than the current size, the string is truncated. If n is larger, the memory is reallocated to exactly this amount, and the additional characters are NULL characters.
| void m2m::String::resize |

|

c |
|
) |
| |
Resize string. If n is less than the current size, the string is truncated. If n is larger, the memory is reallocated to exactly this amount, and the additional characters are c characters.
