StringCompare()

int32_t StringCompare	(	const char *	str1,
		const char *	str2 )

Compares two strings character by character. Returns 0 if the strings are equal, >0 if the first non-matching character in str1 is greater than str2, and <0 if the first non-matching character in str1 is less than str2.

Parameters

str1	First string to compare with
str2	Second string to compare with

Returns

0 if str1 == str2, >0 if the first non-matching character in str1 > str2, and <0 if the first non-matching character in str1 < str2.

StringConcat()

char * StringConcat	(	char *	dest,
		const char *	source )

Appends the content of the string source to the end of the string dest.

Parameters

dest	Destination string to which the source string will be appended
source	Source string to be appended to the destination

Returns

Pointer to the concatenated string (dest + source). The original string is modified

StringConvert()

char * StringConvert

(

int32_t

num

)

Converts an int32_t into a string.

Parameters

num	Integer to convert into a string

Returns

Pointer to a buffer that contains the converted string

StringCopy()

char * StringCopy	(	char *	dest,
		const char *	source )

Copies the string pointed by source (including the null character) to the destination dest.

Parameters

destination	Destination buffer to copy the source string to
source	String to be copied

Returns

Pointer to the copied string.

StringEndsWith()

bool StringEndsWith	(	const char *	str,
		const char *	compareWith )

Checks if the given string str ends with the specified substring compareWith.

Parameters

str	Input string
compareWith	Substring to check for at the end of the string str

Returns

True if the string str ends with compareWith, otherwise false.

StringIndexOf()

int32_t StringIndexOf	(	const char *	str,
		char	c )

Finds and returns the index of first occurance the character c in the string str.

Parameters

str	String to search
c	Character to search for

Returns

Index of the char c in the string str. Returns -1 if the character is not found.

StringIsAlphabetic()

bool StringIsAlphabetic

(

const char *

str

)

Checks if all characters in the input string are alphabetic.

Parameters

True if all characters are alphabetic, otherwise false.

StringIsAlphanumeric()

bool StringIsAlphanumeric

(

const char *

str

)

Checks if all characters in the input string are alphanumeric.

Parameters

str	Input string to check

Returns

True if all characters are alphanumeric, otherwise false.

StringIsLower()

bool StringIsLower

(

const char *

str

)

Checks if all characters in the input string are lowercase characters (can only contain characters)

Parameters

str	Input string to convert

Returns
