4.7 The class PlString

A SWI-Prolog string represents a byte-string on the global stack. It's lifetime is the same as for compound terms and other data living on the global stack. Strings are not only a compound representation of text that is garbage-collected, but as they can contain 0-bytes, they can be used to contain arbitrary C-data structures.

PlString :: PlString(const wchar_t *text)
PlString :: PlString(const char *text)
Create a SWI-Prolog string object from a 0-terminated C-string. The text is copied.
PlString :: PlString(const wchar_t *text, size_t len)
PlString :: PlString(const char *text, size_t len)
Create a SWI-Prolog string object from a C-string with specified length. The text may contain 0-characters and is copied.
