Details

Ibuffer fd_read_to_ibuf(int fd);

int *ibuf_buffer(Ibuffer ibuf);

void ibuf_free(Ibuffer ibuf);
Free an Ibuffer. 
Ibuffer ibuf_init(void);
Allocate and initialize an Ibuffer. 
int ibuf_length(Ibuffer ibuf);

int ibuf_read(Ibuffer ibuf);
Get the next integer from an Ibuffer. This version returns IBUF_EOF (INT_MIN) if there is nothing to read. 
void ibuf_rewind(Ibuffer ibuf);
Reset an Ibuffer for reading. 
void ibuf_write(Ibuffer ibuf, int i);
Write an integer to an Ibuffer. 
void ibuf_write_block(Ibuffer ibuf, int *a, int n);
Write an array of integers to an Ibuffer. 
int ibuf_xread(Ibuffer ibuf);
Get the next integer from an Ibuffer. This version assumes there is an integer to read; if it is at the end IBUF_EOF, a fatal error occurs. 
void p_ibuf(Ibuffer ibuf);
Print a an Ibuffer to a stdout. This is mainly for debugging.
