NAME¶
stralloc_readyplus - provide space in a stralloc
SYNTAX¶
#include <stralloc.h>
int
stralloc_readyplus(stralloc*
sa,size_t
len);
DESCRIPTION¶
stralloc_readyplus makes sure that
sa has enough space allocated to hold
an additional
len bytes: If
sa is not allocated, stralloc_ready
allocates at least
len bytes of space, and returns 1. If
sa is
already allocated, but not enough to hold
len additional bytes,
stralloc_ready allocates at least
sa->len+
len bytes of space,
copies the old string into the new space, frees the old space, and returns 1.
Note that this changes
sa.s.
If stralloc_readyplus runs out of memory, it leaves
sa alone and returns
0.
RETURN VALUE¶
1 for success, 0 on memory allocation failure.
