Thread: g_strdelimit Segmentation fault.

Something stupid must be going on. I really can't figure what I am doing wrong

Code:

#include <stdio.h>
#include <glib.h>

int main(void)
{
    gchar *t="LeftSide:RightSide";
    g_strdelimit(t, ":", '|');
    printf("%s\n",t);
    return 0;
}

According to this :String Utility Functions it should work but the g-strdelimit gives segmentation fault according to gdb.

Code:

    gchar *t="LeftSide:RightSide";

Above, you defined t as a char pointer. It points to a string literal. String literals are read-only in C.

Above, the g_strdelimit() function will try to modify the string pointed to by t, but because it is read-only, you'll get a segmentation violation.

What you intended, obviously, was to declare a string variable, initialized to your string, right? That would be

Code:

    gchar t[] = "LeftSide:RightSide";

The difference between this one and the one you used that here, the string literal only defines the initial value of the char array t, whereas in your code, you defined t to point to the string literal itself.

I was just about to post that I solved it but you replied before I could. I tend to forget about this important detail.
Thanks anyway.
