void argv_free

(

char **

argv

)

argv_free - free an argv - the argument vector to be freed

Frees an argv and the strings it points to.

Definition at line 127 of file string.c.

char** argv_split	(	const char *	str,
		int *	argcp
	)

argv_split - split a string at whitespace, returning an argv : the string to be split : returned argument count

Returns an array of pointers to strings which are split out from . This is performed by strictly splitting on white-space; no quote processing is performed. Multiple whitespace characters are considered to be a single argument separator. The returned array is always NULL-terminated. Returns NULL on memory allocation failure.

Definition at line 148 of file string.c.

void* memdup	(	const void *	src,
		size_t	len
	)

memdup - duplicate region of memory : memory region to duplicate : memory region length

Definition at line 344 of file string.c.

s64 perf_atoll

(

const char *

str

)

Definition at line 10 of file string.c.

char* rtrim

(

char *

s

)

rtrim - Removes trailing whitespace from . : The string to be stripped.

Note that the first trailing whitespace is replaced with a NUL-terminator in the given string . Returns .

Definition at line 323 of file string.c.

bool strglobmatch	(	const char *	str,
		const char *	pat
	)

strglobmatch - glob expression pattern matching : the target string to match : the pattern string to match

This returns true if the matches . can includes wildcards ('*','?') and character classes ([CHARS], complementation and ranges are also supported). Also, this supports escape character ('\') to use special characters as normal character.

Note: if syntax is broken, this always returns false.

Definition at line 280 of file string.c.

bool strlazymatch	(	const char *	str,
		const char *	pat
	)

strlazymatch - matching pattern strings lazily with glob pattern : the target string to match : the pattern string to match

This is similar to strglobmatch, except this ignores spaces in the target string.

Definition at line 293 of file string.c.

int strtailcmp	(	const char *	s1,
		const char *	s2
	)

strtailcmp - Compare the tail of two strings : 1st string to be compared : 2nd string to be compared

Return 0 if whole of either string is same as another's tail part.
