_CP_insert is equivalent to the result = insert(string1, ac.expression, vc.expression, sc.expression, string2) BASIC statement.
int _CP_insert(CPSTR** result, CPSTR* string1, int ac.expression, int vc.expression, int sc.expression, CPSTR* string2)
This function returns -1 if an error occurs. The error code is contained in _CP_errno.
/* Prints "a^b^c". */ CPSTR * s = _CP_mkstr("a\376b"); CPSTR * t = _CP_mkstr("c"); _CP_insert(&s,s,3,0,0,t); _CP_print(s);
