size_twget_strlcpy(char*dst,constchar*src,size_tsize)Parametersdst Output string buffer
src Input string
size Size of dst
Returns
Length of src
Copy string src into dst with overflow checking.
This is the same as snprintf(dst,size,'%s',src) but faster and more elegant.
If src is NULL, the return value is 0 and nothing is written. If \ dst is NULL, the return value is the
length of src and nothing is written.
ssize_twget_strscpy(char*dst,constchar*src,size_tsize)Parametersdst Output string buffer
src Input string
size Size of dst
Returns
Number of copied bytes (excluding trailing 0) or -1 when src doesn't fit into dst
Copy string src into dst with overflow checking.
If either dst is NULL or size is 0, the return value is -1 and nothing is written. If src is NULL and
size is 0, the return value is -1. If src is NULL and size is >0, the return value is 0 and dst is an
empty string.
Else the return value is the number of bytes copied to dst excluding the terminating 0.

values.
intwget_strcasecmp_ascii(constchar*s1,constchar*s2)Parameterss1 String
s2 String
Returns
0 if both s1 and s2 are the same disregarding case for ASCII letters a-z
0 if both s1 and s2 are NULL
<0 if s1 is NULL and s2 is not NULL or s1 is smaller than s2
>0 if s2 is NULL and s1 is not NULL or s1 is greater than s2.
This functions compares s1 and s2 as ASCII strings, case insensitive. It also accepts NULL values.
intwget_strncasecmp_ascii(constchar*s1,constchar*s2,size_tn)Parameterss1 String
s2 String
n Max. number of chars to compare
Returns
0 if both s1 and s2 are the same disregarding case for ASCII letters a-z
0 if both s1 and s2 are NULL
<0 if s1 is NULL and s2 is not NULL or s1 is smaller than s2
>0 if s2 is NULL and s1 is not NULL or s1 is greater than s2.
This functions compares s1 and s2 as ASCII strings, case insensitive, up to a max number of n chars. It
also accepts NULL values.
char*wget_strtolower(char*s)Parameterss String to convert
Returns
Value of s
Converts ASCII string s to lowercase in place.
intwget_strncmp(constchar*s1,constchar*s2,size_tn)Parameterss1 String
s2 String
n Max. number of chars to compare
Returns
0 if both s1 and s2 are the same or if both s1 and s2 are NULL
<0 if s1 is NULL and s2 is not NULL or s1 is smaller than s2
>0 if s2 is NULL and s1 is not NULL or s1 is greater than s2.
This functions compares s1 and s2 in the same way as strncmp() does, except that it also handles NULL
values.
intwget_strncasecmp(constchar*s1,constchar*s2,size_tn)Parameterss1 String
s2 String
n Max. number of chars to compare
Returns
0 if both s1 and s2 are the same disregarding case or if both s1 and s2 are NULL
<0 if s1 is NULL and s2 is not NULL or s1 is smaller than s2
>0 if s2 is NULL and s1 is not NULL or s1 is greater than s2.
This functions compares s1 and s2 in the same way as strncasecmp() does, except that it also handles NULL
values.
voidwget_memtohex(constunsignedchar*src,size_tsrc_len,char*dst,size_tdst_size)Parameterssrc Pointer to input buffer
src_len Number of bytes to encode
dst Buffer to hold the encoded string
dst_size Size of dst in bytes
Encodes a number of bytes into a lowercase hexadecimal C string.
voidwget_millisleep(intms)Parametersms Number of milliseconds to sleep
Pause for ms milliseconds.
longlongwget_get_timemillis(void)
Return the current milliseconds since the epoch.
intwget_percent_unescape(char*src)Parameterssrc String to unescape
Returns
0 if the string did not change
1 if unescaping took place
Does an inline percent unescape. Each occurrence of xx (x = hex digit) will converted into it's byte
representation.
intwget_match_tail(constchar*s,constchar*tail)Parameterss String
tail String
Returns
1 if tail matches the end of s, 0 if not
Checks if tail matches the end of the string s.
intwget_match_tail_nocase(constchar*s,constchar*tail)Parameterss String
tail String
Returns
1 if tail matches the end of s, 0 if not
Checks if tail matches the end of the string s, disregarding the case, ASCII only.
char*wget_strnglob(constchar*str,size_tn,intflags)Parametersstr String to run glob() against
n Length of string
flags Flags to pass to glob()
Returns
Expanded string after running glob
Finds a pathname by running glob(3) on the pattern in the first n bytes of globstr. Returns a newly
allocated string with the first n bytes replaced with the matching pattern obtained via glob(3) if one
was found. Otherwise it returns NULL.
char*wget_human_readable(char*buf,size_tbufsize,uint64_tn)Parametersbuf Result buffer
bufsize Size of /p buf
n Number to convert
Returns
Pointer to printable representation of n
Returns a human readable representation of n. n, a byte quantity, is converted to a human-readable
abbreviated form a la sizes printed by `ls -lh'. The result is written into the provided buffer.
Unlike `with_thousand_seps', this approximates to the nearest unit. Quoting GNU libit: 'Most people
visually process strings of 3-4 digits effectively, but longer strings of digits are more prone to
misinterpretation. Hence, converting to an abbreviated form usually improves readability.'
This intentionally uses kilobyte (KB), megabyte (MB), etc. in their original computer-related meaning of
'powers of 1024'. We don't use the '*bibyte' names invented in 1998, and seldom used in practice.
Wikipedia's entry on 'binary prefix' discusses this in some detail.
intwget_get_screen_size(int*width,int*height)Parameterswidth Number of columns in terminal
height Number of rows in terminal
Returns
Upon successful completion, wget_get_screen_size will return 0, and the values of width and height
will be set accordingly. If an error was encountered, the function will return -1 without touching
the values of width and height.
Get the size of the terminal to which the output is currently printed (stderr). This function accepts two
int pointers and will set their values to the width and height of the active terminal in number of
columns. If either of the parameter is NULL, its value will not be set by the function.
