Thread: Copy a string

Hello

I am trying to copy a string that doesn't have a fixed size.
What is the way to do it?

char *search, *split;
......
search = split; doesn't work

strcpy(search, split); doesn't work

Thank you

Looks like the so-called string isn't null terminated otherwise strcpy() would have worked.
Post more details about the string as it is not easy to figure out what you are getting at.

Well, I am trying to copy the string from buff to search.
I get a seg fault at the strcpy line.

I want to adapt the "search" string and leave the "buf" string intact

Code:

	

        char *search, *buf;
	
	buf = ("Hello");
	search = NULL;

	printf("buf: %s\n", buf);
	strcpy(search, buf);
	
	printf("search: %st\n", search);
	strcat(search, " ");
	printf("buf: %st\n", buf);
	printf("search: %st\n", search);

You have to allocate memory first before copying into search.

Thank you !!

Code:

char *search, *split;
......
strcpy((search = malloc((strlen(split) + 1) * sizeof(char))), split);

sizeof(char) is for clarity, the compiler will(or should) ignore it since it evals to a constant 1.
