.SH NAME
stralloc_readyplus \- provide space in a stralloc
.SH SYNTAX
.B #include <stralloc.h>

int \fBstralloc_readyplus\fP(stralloc* \fIsa\fR,size_t \fIlen\fR);
.SH DESCRIPTION
stralloc_readyplus makes sure that \fIsa\fR has enough space allocated
to hold an additional \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
additional bytes, stralloc_ready allocates at least
\fIsa\fR->len+\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_readyplus runs out of memory, it leaves \fIsa\fR alone and
returns 0.
.SH "RETURN VALUE"
1 for success, 0 on memory allocation failure.
