stralloc_copy(3) Library Functions Manual stralloc_copy(3)NAME
stralloc_copy - copy data into a stralloc
SYNTAX
#include <stralloc.h>
int stralloc_copy(stralloc* sato,stralloc* safrom);
DESCRIPTION
stralloc_copy copies the string stored in safrom into sa. It is the same as stralloc_copyb(&sato, safrom.s, safrom.len). safrom must
already be allocated.
The data that sa previously contained is overwritten and truncated.
If stralloc_copy has trouble allocating memory, it returns 0. Otherwise it returns 1.
RETURN VALUE
1 for success, 0 on memory allocation failure.

buffer_get(3) Library Functions Manual buffer_get(3)NAME
buffer_get - read binary data from buffer
SYNTAX
#include <buffer.h>
ssize_t buffer_get(buffer* b,char* x,size_t len);
DESCRIPTION
Normally buffer_get copies data to x[0], x[1], ..., x[len-1] from the beginning of a string stored in preallocated space; removes these len
bytes from the string; and returns len.
If, however, the string has fewer than len (but more than 0) bytes, buffer_get copies only that many bytes, and returns that number.
If the string is empty, buffer_get first uses a read operation to feed data into the string. The read operation may indicate end of input,
in which case buffer_get returns 0; or a read error, in which case buffer_get returns -1, setting errno approporiately.
The preallocated space and the read operation are specified by b. You must initialize b using buffer_init before calling buffer_get (or use
the pre-initialized buffer_0).
