If you're allocating enough memory to approach SIZE_MAX, you really,
really don't want to zero it first

stralloc
stralloc(3) Library Functions Manual stralloc(3)
NAME
stralloc - dynamically allocated strings
SYNTAX
#include <stralloc.h>
int stralloc_ready(&sa,len);
int stralloc_readyplus(&sa,len);
int stralloc_copy(&sa,&sa2);
int stralloc_copys(&sa,buf);
int stralloc_copyb(&sa,buf,len);
int stralloc_cat(&sa,&sa2);
int stralloc_cats(&sa,buf);
int stralloc_catb(&sa,buf,len);
int stralloc_append(&sa,buf);
int stralloc_0(&sa);
int stralloc_starts(&sa,buf);
stralloc sa = {0};
stralloc sa2 = {0};
unsigned int len;
char *buf;
DESCRIPTION
A stralloc variable holds a string in dynamically allocated space. String length is limited only by memory. String contents are unre-
stricted.
The stralloc structure has three components: sa.s is a pointer to the string, or 0 if it is not allocated; sa.len is the number of bytes in
the string, if it is allocated; sa.a is the number of bytes allocated for the string, if it is allocated. A stralloc variable should be
initialized to {0}, meaning unallocated.
stralloc_ready makes sure that sa has enough space allocated for len characters. It allocates extra space if necessary.
stralloc_readyplus makes sure that sa has enough space allocated for len characters more than its current length. If sa is unallocated,
stralloc_readyplus is the same as stralloc_ready.
stralloc_copy copies sa2 to sa, allocating space if necessary. Here sa2 is an allocated stralloc variable.
stralloc_copys copies a 0-terminated string, buf, to sa, without the 0.
stralloc_copyb copies len characters from buf to sa.
stralloc_cat appends sa2 to sa, allocating space if necessary. If sa is unallocated, stralloc_cat is the same as stralloc_copy.
stralloc_cats and stralloc_catb are analogous to stralloc_copys and stralloc_copyb.
stralloc_append adds a single character, *buf, to sa, allocating space if necessary.
stralloc_0 adds a single 0 character to sa.
stralloc_starts returns 1 if the 0-terminated string buf, without the 0, is a prefix of sa.
ERROR HANDLING
If a stralloc routine runs out of memory, it leaves sa alone and returns 0, setting errno appropriately. On success it returns 1; this
guarantees that sa is allocated.
