#include <stralloc.h> #include <buffer.h> int buffer_get_token_sa(buffer* b,stralloc* sa, const char* charset,size_t setlen);
DESCRIPTIONbuffer_get_token_sa appends data from the b to sa until one of the delimiters in charset is found, NOT overwriting the previous content of sa. That delimiter is also appended to sa.
If reading from the buffer or allocating memory fails, buffer_get_token_sa returns -1 and sets errno appropriately. At that point sa may already contain a partial token.
