Functions
static char *	consume_and_resize (char **s1, size_t len)
	Allocate and return a new string of size len + 1 containing len characters from string pointed to by s1, allocate a new string containing the remainder of the string pointed to by s1, free the original, and set address at s1 to point to the remainder string.
static size_t	find_line_end (char *s, size_t *len)
	Find the first newline in string s and write its index + 1 into len.
static size_t	fill_line_buf (int fd, char **line_buf, size_t *first_line_len)
	Reading from fd, fill and / or allocate line buffer at line_buf, set first_line_len to the length of the first segment ending with a newline or EOF.
char *	get_next_line (int fd)
	Return the next segment of text ending in a newline or EOF from file descriptor fd.

consume_and_resize()

static char * consume_and_resize ( char **  s1, size_t  len  )

static

Allocate and return a new string of size len + 1 containing len characters from string pointed to by s1, allocate a new string containing the remainder of the string pointed to by s1, free the original, and set address at s1 to point to the remainder string.

Parameters

s1	Pointer to address of string to consume from
len	Number of characters to consume

Return values

char*

Allocated consumed section of *s1

fill_line_buf()

static size_t fill_line_buf ( int  fd, char **  line_buf, size_t *  first_line_len  )

static

Reading from fd, fill and / or allocate line buffer at line_buf, set first_line_len to the length of the first segment ending with a newline or EOF.

Parameters

[in]	fd	Integer file descriptor to read from
[in,out]	line_buf	Pointer to address of allocated memory to fill. Address at *line_buf may be NULL
