openreadclose(3) Library Functions Manual openreadclose(3)NAME
openreadclose - read a whole file into a stralloc
SYNTAX
#include <openreadclose.h>
int openreadclose(const char *filename,
stralloc* sa,size_t bufsize);
DESCRIPTION
openreadclose opens the file filename for reading and reads the whole content into the stralloc sa. The file is read in chunks of bufsize
bytes size. If everything worked fine, openreadclose returns 1. If the file did not exist, openreadclose returns 0. On every other
error, openreadclose returns -1 and sets errno appropriately.

buffer_get_new_token_sa_pred(3) Library Functions Manual buffer_get_new_token_sa_pred(3)NAME
buffer_get_new_token_sa_pred - read token from buffer
SYNTAX
#include <stralloc.h>
#include <buffer.h>
int buffer_get_new_token_sa_pred(buffer* b,stralloc* sa,
int (*predicate)(stralloc* * sa));
DESCRIPTION
buffer_get_token_sa_pred copies data from b to sa until predicate(sa) returns 1 or -1.
If predicate returns 1 once a '
' was read, that new-line character is still appended to sa -- use stralloc_chop or stralloc_chomp to get
rid of it. predicate can also return 0 (indicating further input is required to complete the token) or -1 (abort and return -1; use this
if predicate wants to enfore a maximum message size or does timeout handling or detects a malformed message).
If reading from the buffer or allocating memory fails, buffer_get_new_token_sa_pred returns -1 and sets errno appropriately. At that point
sa may already contain a partial token.
On success, buffer_get_new_token_sa_pred returns 0.
If you want to read from a non-blocking socket, use buffer_get_token_sa_pred instead.
