Detailed Description

String Manipulation API.

Function Documentation

rasprintf()

int rasprintf	(	char **	strp,
		const char *	fmt,
			...
	)

asprintf() clone

rpmhex()

char * rpmhex	(	const uint8_t *	p,
		size_t	plen
	)

Return hex formatted representation of bytes.

Parameters

p	bytes
plen	no. of bytes

Returns

hex formatted string (malloc'ed)

rstrcasecmp()

RPM_GNUC_PURE int rstrcasecmp	(	const char *	s1,
		const char *	s2
	)

Locale insensitive strcasecmp(3).

rstrcat()

char * rstrcat	(	char **	dest,
		const char *	src
	)

Concatenate two strings with dynamically (re)allocated memory.

Parameters

dest	pointer to destination string
src	source string

Returns

realloc'd dest with src appended

rstrhash()

RPM_GNUC_PURE unsigned int rstrhash

(

const char *

string

)

String hashing function

Parameters

string

string to hash

Returns

hash id

rstrlcpy()

size_t rstrlcpy	(	char *	dest,
		const char *	src,
		size_t	n
	)

strlcpy() clone: Copy src to string dest of size n. At most n-1 characters will be copied. Always zero-terminates (unless n == 0). Length of src is returned; if retval >= n, truncation occurred.

Parameters

dest	destination buffer
src	string to copy
n	destination buffer size

Returns

length of src string

rstrncasecmp()

RPM_GNUC_PURE int rstrncasecmp	(	const char *	s1,
		const char *	s2,
		size_t	n
	)

Locale insensitive strncasecmp(3).

rstrscat()

char * rstrscat	(	char **	dest,
		const char *	arg,
			...
	)

Concatenate multiple strings with dynamically (re)allocated memory.

Parameters

dest	pointer to destination string
arg	NULL terminated list of strings to concatenate

Returns

realloc'd dest with strings appended

rvasprintf()

int int rvasprintf	(	char **	strp,
		const char *	fmt,
		va_list	ap
	)

vasprintf() clone
