The
fnmatch() function matches patterns according to the globbing rules used by the shell. It checks the string specified by the
string argument to see if it matches the pattern specified by the
pattern argument.
The
flags argument modifies the interpretation of
pattern and
string. The value of
flags is the bitwise inclusive OR of any of the following constants, which are defined in the include file
fnmatch.h.
FNM_NOESCAPE
Normally, every occurrence of a backslash (‘\') followed by a character in pattern is replaced by that character. This is done to negate any special meaning for the character. If the FNM_NOESCAPE flag is set, a backslash character is treated as an ordinary character.
FNM_PATHNAME
Slash characters in string must be explicitly matched by slashes in pattern. If this flag is not set, then slashes are treated as regular characters.
FNM_PERIOD
Leading periods in strings match periods in patterns. The definition of ``leading'' is related to the specification of FNM_PATHNAME. A period is always ``leading'' if it is the first character in string. Additionally, if FNM_PATHNAME is set, a period is ``leading'' if it immediately follows a slash.
FNM_LEADING_DIR
Ignore “/*” rest after successful pattern matching.
FNM_CASEFOLD
The pattern is matched in a case-insensitive fashion.
