Hi,

You are right.
A correct, working version of a code (with casting) should be:
Code:
int ToLower(string my_input)
  {
         int string_length = my_input.length();
         for (int i=0; i<string_length; i++) {
    my_input[i]=char(tolower(my_input[i]));
      }
  return 0;
  }

Thanks.

TIFFWarning(3tiff)					 Introduction to Library Functions					TIFFWarning(3tiff)

NAME
TIFFWarning, TIFFSetWarningHandler - library warning interface SYNOPSIS
#include <tiffio.h> void TIFFWarning(const char* module, const char* fmt, ...) #include <stdarg.h> typedef void (*TIFFWarningHandler)(const char* module, const char* fmt, va_list ap); TIFFWarningHandler TIFFSetWarningHandler(TIFFWarningHandler handler); DESCRIPTION
TIFFWarning invokes the library-wide warning handler function to (normally) write a warning message to stderr. The fmt parameter is a printf(3S) format string, and any number of arguments can be supplied. The module parameter is interpreted as a string that, if non-zero, should be printed before the message, and is typically used to identify the software module in which a warning is detected. Applications that desire to capture control in the event of a warning should use TIFFSetWarningHandler to override the default warning han- dler. A NULL(0) warning handler function may be installed to suppress error messages. RETURN VALUES
TIFFSetWarningHandler returns a reference to the previous error handling function. ATTRIBUTES
