char * | terminate_string (char *string, char c) |
Add character c to the end of a string after removing terminating carriage returns/linefeeds if any. | |
char * | trim_string (char *string) |
Trims whitespace from the beginning and end of the character string, including carriage return / linefeed characters. | |
char * | trim_string (char *string, char c) |
Similar to above, but trims the string starting at the first occurrence of c. | |

WvString | hostname () |
WvString | fqdomainname () |
WvString | metriculate (const off_t i) |
Inserts SI-style spacing into a number (eg passing 9876543210 returns "9 876 543 210"). |
|
Returns a string with a backslash in front of every non alphanumeric character in s1.

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. Definition at line 410 of file strutils.cc. References WvString::edit(), and WvStringParm. |
|
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. Definition at line 181 of file strutils.cc.

Returns true if 'c' is a newline or carriage return character. Increases code readability a bit. Definition at line 234 of file strutils.cc. |

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". Definition at line 364 of file strutils.cc.

In-place modify a character string so that all contained letters are in upper case. Returns 'string'. Definition at line 152 of file strutils.cc. |
|
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. Definition at line 26 of file strutils.cc. |

Similar to above, but trims the string starting at the first occurrence of c.

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.
