Description

The basic_string class provides a generic template for a dynamically- sized character sequence. This is most commonly used through the string typedef (for basic_string<char>).

For example, to create a string on the device with its contents copied from a C-string on the host:

boost::compute::string str("hello, world!");

  30. basic_string< CharT, Traits > 
    substr(size_type pos = 0, size_type count = npos) const;
  31. size_type find(CharT ch, size_type pos = 0) const;
    Finds the first character ch.
  32. size_type find(basic_string & str, size_type pos = 0) const;
    Finds the first substring equal to str.
  33. size_type find(const char * s, size_type pos = 0) const;

    Finds the first substring equal to the character string pointed to by s. The length of the string is determined by the first null character.

    For example, the following code

    
    

    will return 5 as position.
