.TH stralloc_readyplus 3
|
|
.SH NAME
|
|
stralloc_readyplus \- provide space in a stralloc
|
|
.SH SYNTAX
|
|
.B #include <libowfat/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.
