# stralloc\_readyplus(3)

provide space in a stralloc

## NAME

stralloc\_readyplus - provide space in a stralloc

## SYNTAX

**#include \<libowfat/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.
