Introduction to Library Functions                     STRMATCH(3)

NAME
     strmatch - match shell file patterns

SYNOPSIS
     int strmatch(char* s, char* p)
     char* submatch(char* s, char* p, int m)

DESCRIPTION
     strmatch compares the string s with the shell pattern p  and
     returns  1 for match and 0 otherwise.  submatch does a lead-
     ing substring match of the shell pattern p with  the  string
     s.  If m is 0 then the match is minimal, otherwise a maximal
     match is done.  A pointer to the first character  after  the
     matched substring is returned, 0 if there is no match.

     Except for & and !, each shell  pattern  has  an  equivalent
     egrep(1) construct.

BUGS
     An unbalanced ) terminates the top level pattern.
     Nested & and !  constructs are non-intuitive and are  compu-
     tationally intensive.
