* Leading and trailing whitespaces are ignored.
|
|
*
|
|
* If the string is empty or consists only of only whitespaces, 0 is returned.
|
|
*
|
|
* Digits is parsed as decimal unless the first digit is '0', in which case
|
|
* digits is parsed as octal.
|
|
*
|
|
* The multiplier is case-insensitive. K, M, and G multiply the quantity by
|
|
* 2**10, 2**20, and 2**30, respectively.
|
|
*
|
|
* For backwards compatibility, ill-formatted values are handled as follows:
|
|
* - No leading digits: value is treated as '0'
|
|
* - Invalid multiplier: multiplier is ignored
|
|
* - Invalid characters between digits and multiplier: invalid characters are
|
|
* ignored
|
|
* - Integer overflow: The result of the overflow is returned
|
|
*
|
|
* In any of these cases an error string is stored in *errstr (caller must
|
|
* release it), otherwise *errstr is set to NULL.
