Functions 3

fnstring fromCString(const(char) * cstr) pure nothrowConverts a null-terminated C string to a D string (copying the data).

fnconst(char) * toCString(string s) pure nothrowConverts a D string to a null-terminated C string.

fnconst(char) * toOwnedCString(string s) nothrowConverts a D string to a null-terminated C string backed by owned GC memory.
