This file provides the implementation of ft_split_charset, a string utility that splits a C string into substrings using a set of delimiter characters (charset). Each resulting substring is dynamically allocated and returned as part of a NULL-terminated array.

Internal helper functions:

• ft_is_charset: checks if a character belongs to a charset.
• ft_w_count_charset: counts how many substrings will be created.
• ft_fill_array_charset: populates the output array with substrings.

Function Documentation

ft_fill_array_charset()

static int ft_fill_array_charset ( char **  array, char *  s, char *  charset, size_t  field_count  )

static

Fills an array of substrings from the input string.

Allocates and copies substrings from s into the array using the set of delimiter characters. If allocation fails at any point, previously allocated substrings are freed.

Parameters

array	The output array of substrings.
s	The input string to split.
charset	The set of delimiter characters.
field_count	The number of substrings to extract.

Returns

1 on success, 0 on allocation failure.

ft_is_charset()

static int ft_is_charset ( char  c, const char *  charset  )

static

Checks if a character belongs to a charset.

Iterates through the charset and returns 1 if the character c is found. Otherwise, returns 0.

Parameters

c	The character to check.
charset	The set of delimiter characters.

Returns

1 if the character is in the charset, 0 otherwise.

ft_w_count_charset()

static size_t ft_w_count_charset ( char *  str, char *  charset  )

static

Counts the number of substrings in a split.

Traverses the input string and counts how many substrings would result from a split based on the given charset.

Parameters

str	The input string to split.
charset	The set of delimiter characters.

Returns

The number of expected substrings.
