#define FILE_PATH_REGEX   "((\\.|\\.\\.)?\\/)?(([A-Z]|[a-z]|[0-9]| |-|_|'|\\.)+\\/?)+"

This is the Regular Expression that will be used to check the validity of a path

Function Documentation

int evaluateAndSearch	(	const char **	expression,
		int	exprLen,
		char *	folder,
		List **	result
	)

Evaluates an expression and searches for matching files

Parameters

expression	The expression to search with (as an array of terms)
exprLen	The length of the expression
folder	The folder to search from
result	A List to put the results of the search in

Returns

0 if the search was ok, 1 otherwise

searchType getSearchType	(	const char *	param,
		const char *	arg
	)

Converts a search word to a searchType

Parameters

param	the search word
arg	the parameter linked to the search word

Returns

the corresponding searchType or -1 if no match exists

int getSize

(

const char *

sizeAsString

)

Converts a size with its Unit suffix (K, M, G, T) to the correct size

Parameters

sizeAsString

The size with its suffix

Returns

The size as an integer value

struct timespec* getTimeSpec

(

const char *

date

)

Function to convert a date in YYYY-MM-DD format to a timespec

Parameters

date	The date as a String in the format YYYY-MM-DD

Returns

The date as a a pointer of struct timespec

int isBooleanOp

(

const char *

word

)

Checks if a word is a boolean operator

Parameters

word	the word to check

Returns

1 if it is a boolean operator, 0 otherwise

int isValidPath

(

const char *

path

)

Function to check if a path is valid

Parameters

path	The path we want to check

Returns

1 if the path is valid, 0 otherwise

int isValidSearch	(	searchType	st,
		const char *	arg
	)

Checks if a searchType has proper argument linked to it

Parameters

st	The search type
arg	The argument

Returns

1 if the search is valid, 0 otherwise

const void* prepareArgument	(	searchType	st,
		const char *	arg
	)

Function that returns a generic pointer to an argument for a search of a certain type It will actually return the pointer for the correct type depending on the search

Parameters

st	The type of search
arg	The argument as a string

Returns

A pointer to the argument in the correct type

const char* trimArgument	(	searchType	st,
		const char *	arg
	)

Removes the + or - before a search argument if necessary

Parameters

st	searchType
arg	argument to trim

Returns

Trimmed argument
