string-to-base64-string

Arguments: usb8-array &key (wrap-at-column 52) start end external-format

This function is similar to usb8-array-to-base64-string except it takes a string rather than a usb8 array as its argument and also allows specification of an external format with the external-format keyword argument (which defaults to (crlf-base-ef :latin1), see crlf-base-ef). See also base64-string-to-string.

Like usb8-array-to-base64-string and related functions, the arguments to this function were changed in release 8.1 to include the keyword arguments. The wrap-at-column keyword argument was an optional argument in earlier releases and a call with its value specified as if for an optional argument (i.e. (string-to-base-64-string "bother" 23) is accepted thugh discouraged. No other keyword argument may be specified if the optional argument style is used.
