extern int \fBstralloc_ready\fP(stralloc* \fIsa\fR,unsigned int \fIlen\fR);
stralloc_ready makes sure that \fIsa\fR has enough space allocated to hold
\fIlen\fR bytes: If \fIsa\fR is not allocated, stralloc_ready allocates at least
\fIlen\fR bytes of space, and returns 1. If \fIsa\fR is already allocated, but
not enough to hold \fIlen\fR bytes, stralloc_ready allocates at least \fIlen\fR
bytes of space, copies the old string into the new space, frees the
old space, and returns 1. Note that this changes \fIsa\fR.s.
If stralloc_ready runs out of memory, it leaves \fIsa\fR alone and
returns 0.
