UNSAFE INTERFACE CText;

IMPORT Ctypes;

PROCEDURE SharedTtoS(t: TEXT): Ctypes.char_star;
Returns a C string equal to the given text, and sharing the same storage if possible. To keep the garbage collector from moving the string, a reference to it must be kept on the stack while it is being used. The string must be freed with FreeSharedS.

PROCEDURE FreeSharedS(t: TEXT; s: Ctypes.char_star);
Free a C string which was produced by SharedTtoS, if necessary.

PROCEDURE CopyMtoT(mem: Ctypes.void_star; len: CARDINAL): TEXT;
Create a text from a sequence of bytes.

PROCEDURE CopyQuotedMtoT(mem: Ctypes.void_star; len: CARDINAL): TEXT;
Like CopyMtoT, but converts doubled @ characters into single @ characters.

END CText.
