This file implements the ft_split function, which breaks a string into an array of substrings based on a single delimiter character. Substrings are dynamically allocated, and the output is a NULL-terminated array. Internal helpers handle word counting and array filling.

Function Documentation

ft_fill_array()

static int ft_fill_array ( char **  array, const char *  s, char  c, size_t  w_count  )

static

Fills the output array with substrings from input.

Allocates substrings from s using ft_substr and stores them in the provided array. The array is NULL-terminated. On allocation failure, previously allocated substrings are freed.

Parameters

array	The output array of substrings.
s	The input string to split.
c	The delimiter character.
w_count	The number of substrings to extract.

Returns

1 on success, 0 on failure.

ft_w_count()

static size_t ft_w_count ( const char *  str, char  c  )

static

Counts how many substrings will result from splitting.

Traverses the input string and counts how many substrings (non-empty sequences not interrupted by the delimiter) will be generated.

Parameters

str	The input string to scan.
c	The delimiter character.

Returns

The number of substrings (words) in the input.
