|
Add character c to the end of a string after removing terminating carriage returns/linefeeds if any. You need a buffer that's at least one character bigger than the current length of the string, including the terminating NULL. |
|
Trims whitespace from the beginning and end of the character string, including carriage return / linefeed characters. Modifies the string in place. Returns the new first character of the string, which points either at 'string' itself or some character contained therein. string is allowed to be NULL; returns NULL in that case. |
|
return the string formed by concatenating string 'a' and string 'b' with the 'sep' character between them. For example, spacecat("xx", "yy", ";"); returns "xx;yy", and spacecat("xx;;", "yy", ";") returns "xx;;;yy", and spacecat("xx;;", "yy", ";", true) returns "xx;yy". This function is much faster than the more obvious WvString("%s;%s", a, b), so it's useful when you're producing a *lot* of string data. |
|
Replace all instances of c1 with c2 for the first 'length' characters in 'string'. Ignores terminating NULL, so make sure you set 'length' correctly. |
|
In-place modify a character string so that all contained letters are in lower case. Returns 'string'. |
|
In-place modify a character string so that all contained letters are in upper case. Returns 'string'. |
|
Produce a hexadecimal dump of the data buffer in 'buf' of length 'len'. It is formatted with 16 bytes per line; each line has an address offset, hex representation, and printable representation. This is used mostly for debugging purposes. You can send the returned WvString object directly to a WvLog or any other WvStream for output. |
|
Returns true if 'c' is a newline or carriage return character. Increases code readability a bit. |
|
Converts escaped characters (things like 20 etc.) from web URLS into their normal ASCII representations. If you happen to be decoding PEM encoded stuff,or anything that has + signs in it that you don't want encoded as spaces, then set no_space to true, and it should "just work" for you. |
|
Similar to crypt(), but this randomly selects its own salt. Before calling this function, you should call srandom(). When 2 identical strings are encrypted, they will not return the same encryption. Also, str does not need to be less than 8 chars as UNIX crypt says, although it only works on the first 8 characters. |

Similar to crypt(), but this randomly selects its own salt. Before calling this function, you should call srandom(). When 2 identical strings are encrypted, they will not return the same encryption. Also, str does not need to be less than 8 chars as we're using the glibc md5 algorithm. |
|
Given a hostname, turn it into a "nice" one. It has to start with a letter/number, END with a letter/number, have underscores converted to hyphens, and have no more than one hyphen in a row. If we can't do this and have any sort of answer, return "UNKNOWN". |
|
Take a full path/file name and splits it up into respective pathname and filename. This can also be useful for splitting the toplevel directory off a path. |
|
Finds a string in an array and returns its index. Returns -1 if not found. |
|
Splits a string and adds each substring to a collection. coll : the collection of strings to add to _s : the string to split splitchars : the set of delimiter characters limit : the maximum number of elements to split |
|
Splits a string and adds each substring to a collection. this behaves differently in that it actually delimits the pieces as fields and returns them, it doesn't treat multiple delimeters as one and skip them. ie., parm1::parm2 -> 'parm1','','parm2' when delimited with ':' coll : the collection of strings to add to _s : the string to split splitchars : the set of delimiter characters limit : the maximum number of elements to split |
|
Concatenates all strings in a collection and returns the result. coll : the collection of strings to read from joinchars : the delimiter string to insert between strings |
|
Replace any instances of "a" with "b" in "s". Kind of like sed, only much dumber. |
|
Returns everything in line (exclusively) after a. If a is not in line, "" is returned. |
|
Returns everything in line (exclusively) before 'a'. If a is not in line, line is returned. |
|
Returns the string of length len starting at pos in line. Error checking prevents seg fault. If pos > line.len()-1 return "" if pos+len > line.len() simply return from pos to end of line |
