buffer_getline3diet
Read line from buffer
Usage
#include <buffer.h>
ssize_t buffer_getline(buffer* b,char* x,size_t len);
Overview
buffer_getline copies data from b to x[0], x[1], ..., x[len-1] until len bytes have been copied or a new-line character ('\n') is encountered. That character is also copied.
Note that line is not 0-terminated to make reading lines with 0-bytes possible through this interface.
Return value
Number of bytes read (without '\n'), -1 on error (setting errno).
