Strsep and iCalendar parsing in C
I'm having trouble parsing a simple iCalendar file in C.
char * description, * identifier, *tofree;
tofree = description = strdup(string);
identifier = strsep(&description, ":");
printf("{%s}\n", identifier);
printf("[%s]\n", description);
free(tofree);
string would be the line I just read from the file, such as:
BEGIN:VCALENDAR
When I run this program, I get the following output:
{BEGIN}
]VCALENDAR
Can someone please help me determine what's causing this issue? The output should show "[VCALENDAR]" and I'm not sure why this is occurring.

Your input data ends with a carriage return, \r. Your code outputs:
[VCALENDAR\r]\n
and the carriage return places the cursor at the start of the line so the ] overwrites your [.
It's probably best to remove the line ending before scanning; failing that, include \r and \n in the delimiters provided to strsep(), but you'd have to use strsep() a second time to get the VCALENDAR token.
