           Summary: fscanf scan sets do not support embedded character
                    classes
           Product: glibc
           Version: 2.11
            Status: NEW
          Severity: normal
          Priority: P2
         Component: manual
        AssignedTo: roland@gnu.org
        ReportedBy: giecrilj@stegny.2a.pl


libc.info, 12.14.5: String Input Conversions:

You specify the set between the `[' character and a following `]' character,
using the same syntax used in regular expressions.

man regexp(7):

Within a bracket expression, the name of a character class enclosed in "[:" and
":]" stands for the list of all characters belonging to that class.

However, my experiment shows that [:character-classes:] are not supported
within scan sets.

sscanf("A", "%*[[:alpha:]]");
