Functions
char *	strnstr (const char *haystack, const char *needle, size_t size)
	A bounded version of strstr. Conforms to BSD semantics.
char *	strndup (const char *s, size_t n)
	Return a pointer to a new string, which is a duplicate of the string s (or, if necessary, which contains the first nn bytes of s plus a terminating null).
int	strsort (const void *p1, const void *p2)
	Sort function for sorting strings with qsort().
int	strsort_reverse (const void *p1, const void *p2)
	Order-reversed version of strsort().
int	scnprintf (char *text, size_t maxlen, const char *fmt,...)
	Like snprintf(), but returns the number of characters ACTUALLY "printed" into the buffer. This makes it possible to chain these calls to concatenate into a buffer without introducing a potential bug every time. This call was first added to the Linux kernel by Juergen Quade.
int	num2str (char dest[NUM2STRLEN], double n, int decimals)
	Converts a numeric value to a string.
const char *	num2strU (double n, int decimals)
	Unsafe version of num2str that uses an internal buffer. Every call overwrites the return value.
void	print_with_line_numbers (const char *str)
	Prints to stderr with line numbers.

Function Documentation

num2str()

int num2str	(	char	dest[NUM2STRLEN],
		double	n,
		int	decimals )

Converts a numeric value to a string.

Parameters

[out]	dest	String to write to.
	n	Number to write.
	decimals	Number of decimals to write.

Definition at line 123 of file nstring.c.

num2strU()

const char * num2strU	(	double	n,
		int	decimals )

Unsafe version of num2str that uses an internal buffer. Every call overwrites the return value.

Parameters

n	Number to write.
decimals	Number of decimals to write.

Returns

Fancy string number.

Definition at line 163 of file nstring.c.

print_with_line_numbers()

void print_with_line_numbers

(

const char *

str

)

Prints to stderr with line numbers.

Parameters

str	String to print.

Definition at line 175 of file nstring.c.

scnprintf()

int scnprintf	(	char *	text,
		size_t	maxlen,
		const char *	fmt,
			... )

Like snprintf(), but returns the number of characters ACTUALLY "printed" into the buffer. This makes it possible to chain these calls to concatenate into a buffer without introducing a potential bug every time. This call was first added to the Linux kernel by Juergen Quade.

Definition at line 102 of file nstring.c.

strndup()

char * strndup	(	const char *	s,
		size_t	n )

Return a pointer to a new string, which is a duplicate of the string s (or, if necessary, which contains the first nn bytes of s plus a terminating null).

Taken from glibc. Conforms to POSIX.1-2008.

Definition at line 69 of file nstring.c.

strnstr()

char * strnstr	(	const char *	haystack,
		const char *	needle,
		size_t	size )

A bounded version of strstr. Conforms to BSD semantics.

Parameters

haystack	The string to search in
size	The size of haystack
needle	The string to search for

Returns

A pointer to the first occurrence of needle in haystack, or NULL

Definition at line 26 of file nstring.c.

strsort()

int strsort	(	const void *	p1,
		const void *	p2 )

Sort function for sorting strings with qsort().

Definition at line 83 of file nstring.c.

strsort_reverse()

int strsort_reverse	(	const void *	p1,
		const void *	p2 )

Order-reversed version of strsort().
