* patmatch - match shell-like patterns

|
|
* patmatch() returns whether given string @s matches the given shell-like
|
|
* pattern @p. The patterns consist of characters (which are matched literally),
|
|
* question marks which match any single character, asterisks which match any
|
|
* (possibly empty) string of characters and backslashes which are used to
|
|
* escape any special characters and force them to be treated literally.
|
|
*
|
|
* The matching process is not optimized with respect to time, so please
|
|
* avoid using this function for complex patterns.
