* Name: fnmatch
|
||
|
|
*
|
||
|
|
* Description:
|
||
|
|
* The fnmatch() function shall match patterns as described in the Shell
|
||
|
|
* and Utilities volume of IEEE Std 1003.1-2001, Section 2.13.1, Patterns
|
||
|
|
* Matching a Single Character, and Section 2.13.2, Patterns Matching
|
||
|
|
* Multiple Characters. It checks the string specified by the string
|
||
|
|
* argument to see if it matches the pattern specified by the pattern
|
||
|
|
* argument.
|
||
|
|
*
|
||
|
|
* The flags argument shall modify the interpretation of pattern and
|
||
|
|
* string. It is the bitwise-inclusive OR of zero or more of the flags
|
||
|
|
* defined in <fnmatch.h>. If the FNM_PATHNAME flag is set in flags,
|
||
|
|
* then a slash character ( '/' ) in string shall be explicitly matched
|
||
|
|
* by a slash in pattern; it shall not be matched by either the asterisk
|
||
|
|
* or question-mark special characters, nor by a bracket expression. If
|
||
|
|
* the FNM_PATHNAME flag is not set, the slash character shall be treated
|
||
|
|
* as an ordinary character.
|
||
|
|
*
|
||
|
|
* If FNM_NOESCAPE is not set in flags, a backslash character ( '\' ) in
|
||
|
|
* pattern followed by any other character shall match that second
|
||
|
|
* character in string. In particular, "\\" shall match a backslash in
|
||
|
|
* string. If FNM_NOESCAPE is set, a backslash character shall be treated
|
||
|
|
* as an ordinary character.
|
||
|
|
*
|
||
|
|
* If FNM_PERIOD is set in flags, then a leading period ( '.' ) in string
|
||
|
|
* shall match a period in pattern; as described by rule 2 in the Shell and
|
||
|
|
* Utilities volume of IEEE Std 1003.1-2001, Section 2.13.3, Patterns Used
|
||
|
|
* for Filename Expansion where the location of "leading" is indicated by
|
||
|
|
* the value of FNM_PATHNAME:
|
||
|
|
*
|
||
|
|
* If FNM_PATHNAME is set, a period is "leading" if it is the first
|
||
|
|
* character in string or if it immediately follows a slash.
|
||
|
|
*
|
||
|
|
* If FNM_PATHNAME is not set, a period is "leading" only if it is the
|
||
|
|
* first character of string.
|
||
|
|
*
|
||
|
|
* If FNM_PERIOD is not set, then no special restrictions are placed on
|
||
|
|
* matching a period.
|
||
|
|
*
|
||
|
|
* Returned Value:
|
||
|
|
* If string matches the pattern specified by pattern, then fnmatch()
|
||
|
|
* shall return 0. If there is no match, fnmatch() shall return
|
||
|
|
* FNM_NOMATCH, which is defined in <fnmatch.h>. If an error occurs,
|
||
|
|
* fnmatch() shall return another non-zero value.
