strrtrim()

Synopsis

string strrtrim(string s [, string trimstr]);

Parameters

Return value

Trimmed string

Errors

Missing or incorrect arguments

Description

Cuts the characters in the string trimstr out of the string s, from right to left, and returns the thus trimmed string s. As soon as a character occurs in s that does not occur in trimstr the operation is terminated. If trimstr is empty or not a string, the untrimmed string s is returned. trimstr is optional, by default a trim string containing white spaces is used. This trims trailing spaces, tabs, returns etc. from s.

Note that the second parameter of this function defines a list of characters to be deleted and not a string, which should be deleted!

Example

The following example trims all the characters ".as" from the string s until it encounters the first character not contained in the trim string.

main()
{
  string s;
  s="Nameasas.asas..as";
  s=strrtrim(s, ".as"); // Result "Name"
  DebugN(s); // Print the result
}
