Instance Method

getCString(_:maxLength:)

Invokes getCString(_:maxLength:range:remaining:) with maxLength as the maximum length in char-sized units, the receiver’s entire extent as the range, and NULL for the remaining range.

Declaration

func getCString(_ bytes: UnsafeMutablePointer<Int8>, maxLength: Int)

Discussion

buffer must be large enough to contain maxLength chars plus a terminating zero char (which this method adds).

Raises an NSCharacterConversionException if the receiver can’t be represented in the default C-string encoding without loss of information. Use canBeConverted(to:) if necessary to check whether a string can be losslessly converted to the default C-string encoding. If it can’t, use lossyCString() or data(using:allowLossyConversion:) to get a C-string representation with some loss of information.
