-> | Try in you program.c the following line:
-> | 
-> | val = fscanf(file,"%*[ \t\n]%74[abcdefghijklmnopqrstuvwxyz
-> | ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789]", namebuf);
-> | 
-> | In case your input does not begin with space, tab or newline, scanf will

-> +---------------

But the following code would work on any unix system I've ever encountered:

	val = fscanf(file, " %74[a-zA-Z0-9]", namebuf);

Whitespace in the format string matches OPTIONAL whitespace in the input
stream.  The %[] format requires that SOMETHING match its scanstring.
The * only means "0 or more" in regular expressions.  In the example
above it is being used to suppress storing the result of the match.
