Synopsis

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

Parameters

Return value

A shortened string

Errors

Missing or incorrect arguments

Description

Removes the characters contained in the string trimstr from left to right from the string s and returns the shortened string s. As soon as a character occurs, on comparison, in s, that does not occur in trimstr, the operation is ended. If trimstr is empty or not a string, the unshortened string s is returned. trimstr is optional, by default a trim string comprising white spaces is used. Blank spaces, tabs, line feeds etc. as leading characters of s are removed.

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

Example

Removes "ETM" from "ETMWinCCOA" and returns "WinCCOA". The function removes characters from the string until a character that is not on the list, is found.

main()
{
  string res;
  res=strltrim("ETMWinCCOA", "ETM");
  DebugN("Shortened string:", res);
  }
