Function PQgetline

src/interfaces/libpq/fe-exec.c:2745–2759

* PQgetline - gets a newline-terminated string from the backend. * * Chiefly here so that applications can use "COPY to stdout" * and read the output string. Returns a null-terminated string in s. * * XXX this routine is now deprecated, because it can't handle binary data. * If called during a COPY BINARY we return EOF. * * PQgetline reads up to maxlen-1 characters (like fgets(3)) b

 *		1 in other cases (i.e., the buffer was filled before \n is reached)
