int match_hex	(	substring_t *	s,
		int *	result
	)

match_hex: - scan a hex representation of an integer from a substring_t : substring_t to be scanned

Returns

: resulting integer on success

Description: Attempts to parse the &substring_t as a hexadecimal integer. On success, sets

Returns

to the integer represented by the string and returns 0. Returns either -ENOMEM or -EINVAL on failure.

int match_int	(	substring_t *	s,
		int *	result
	)

match_int: - scan a decimal representation of an integer from a substring_t : substring_t to be scanned

Returns

: resulting integer on success

Description: Attempts to parse the &substring_t as a decimal integer. On success, sets

Returns

to the integer represented by the string and returns 0. Returns either -ENOMEM or -EINVAL on failure.

int match_octal	(	substring_t *	s,
		int *	result
	)

match_octal: - scan an octal representation of an integer from a substring_t : substring_t to be scanned

Returns

: resulting integer on success

Description: Attempts to parse the &substring_t as an octal integer. On success, sets

Returns

to the integer represented by the string and returns 0. Returns either -ENOMEM or -EINVAL on failure.

(

s

)

match_strdup: - allocate a new string with the contents of a substring_t : &substring_t to copy

Description: Allocates and returns a string filled with the contents of the &substring_t . The caller is responsible for freeing the returned string with kfree().

size_t match_strlcpy	(	char *	dest,
		const substring_t *	src,
		size_t	size
	)

match_strlcpy: - Copy the characters from a substring_t to a sized buffer : where to copy to : &substring_t to copy : size of destination buffer

Description: Copy the characters in &substring_t to the c-style string . Copy no more than - 1 characters, plus the terminating NUL. Return length of .

int match_token	(	char *	s,
		const match_table_t	table,
		substring_t	args[]
	)

match_token: - Find a token (and optional args) in a string : the string to examine for token/argument pairs : match_table_t describing the set of allowed option tokens and the arguments that may be associated with them. Must be terminated with a &struct match_token whose pattern is set to the NULL pointer. : array of MAX_OPT_ARGS &substring_t elements. Used to return match locations.

Description: Detects which if any of a set of token strings has been passed to it. Tokens can include up to MAX_OPT_ARGS instances of basic c-style format identifiers which will be taken into account when matching the tokens, and whose locations will be returned in the array.
