string-to-octets

Arguments: string &key (null-terminate t) (start 0) (end (length string)) mb-vector make-mb-vector? (external-format :default)

In releases prior to 6.0, this function was named string-to-mb. The old name is preserved for backward compatibility, but users should use the new name.

This function returns a Lisp (simple-array (unsigned-byte 8) (*)) vector and the number of bytes copied.

This function converts (according to the external-format argument) and copies the string data from indices specified by start to end out of the lisp string into a lisp array of type (simple-array (unsigned-byte 8) (*)). This array is returned.

If the mb-vector argument is specified, then its value will be used (and returned) as the destination lisp array. If a vector is specified with the mb-vector argument and it is not long enough, an error is signaled unless make-mb-vector? is specified as non-nil, in which case a new vector is created and returned (and mb-vector is ignored).

When the null-terminate argument is true, the copied string data (in the resulting vector) is null-terminated, that is the byte following the last data element is 0. The number of 8-bit bytes copied including the null-terminator is returned as the second value of this function.

Conversion is done using the specified external-format. If external-format is not specified (or, equivalently, if the value of external-format is :default), then the external format returned by the following form is used:

(locale-external-format *locale*)

See locale-external-format and *locale*.
