readlink segmentation fault

[Schwarzhelm]

 if( S_ISLNK(mode) )
			{ 
				type = 'l'; /*symlink*/
				readlink(fileName, buf, sizeof(buf));
				printf("\n %s \n",buf);

				
			}

I have this and I keep getting segmentation faults. All I am trying to do is print out the location of a symbolic link. Any suggestions?

Very difficult to say for certain without knowing exactly what readlink() does, but segmentation faults usually arise when you write over the end of allocated memory. My suspicion would be on buf. How is it declared? Is it big enough to hold the string? Is sizeof(buf) giving you the answer you expect?

I have buf declared as a char *buf. I tried the code that was suggested and it is still getting a segmentation fault. filename is dirp->d_name after a lstat.

Thank you.
