No the search is line-by-line, fgets gets one line at a time. tmp[256] can read in as many as 255 chars. No line in the example text is longer than 40. No issue.

As a general solution, use tmp[LINE_MAX] where LINE_MAX is defined in limits.h Most UNIX tools limit line size to whatever LINE_MAX is for your system.
