I am trying to add a new filetype to wiretap to allow for the reading of my
custom file type, a pure text file. When trying to read the first line during
the initial myfile_open routine, the file_gets or file_read fail with a
segmentation fault. If I do my own fopen for the filename, all is good, but
when using wth->fh, it fails. I have copied the format found in other
wiretap/*c files and don't see my error.
If the length of the buffer == 1, then the calls work, if the buffer length is
anything greater than 1, it fails. The same form when using a private fopen to
the same file works just fine. The SIGSEGV happens during the read command.
int myfile_open(wtap *wth, int *err, gchar **err_info _U_) {
guchar *input_line = NULL; input_line = g_malloc(1000*sizeof(guchar));
if((file_gets(input_line, 1000, wth->fh)) == NULL) { printf("Error on
file_gets 0x%0x\n",file_error(wth->fh)); return FALSE; }
As always, thanks for your help with this.Alex Lindberg
