Description H.J. Lu 2011-03-30 13:41:09 UTC 
[hjl@gnu-4 tmp]$ cat x.c
#include <string.h>

char *foo(const char *filename) {
  char *splitpos;

  splitpos = strrchr(filename, '/');
  return splitpos;
}
[hjl@gnu-4 tmp]$ g++ x.c
x.c: In function \u2018char* foo(const char*)\u2019:
x.c:6:35: error: invalid conversion from \u2018const char*\u2019 to \u2018char*\u2019

Comment 1 Jakub Jelinek 2011-03-30 13:43:32 UTC 
THat is completely intentional, C++ says that strchr etc. is
const char *strchr (const char *, int);
char *strchr (char *, int);
