.TH stralloc_ready 3 |

.SH NAME |
|
stralloc_ready \- provide space in a stralloc |
|
.SH SYNTAX |
|
.B #include <stralloc.h> |
|
|
|
int \fBstralloc_ready\fP(stralloc* \fIsa\fR,unsigned int \fIlen\fR); |
|
.SH DESCRIPTION |
|
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. |
