This section describes the flags that you can specify in the
flags argument to
glob. Choose the flags you want,
and combine them with the C bitwise OR operator
glob. This way you can effectively expand several words as if they were concatenated with spaces between them.
In order for appending to work, you must not modify the contents of the
word vector structure between calls to
glob. And, if you set
GLOB_DOOFFS in the first call to
glob, you must also
set it when you append to the results.
Note that the pointer stored in
gl_pathv may no longer be valid
after you call
glob the second time, because
have relocated the vector. So always fetch
gl_pathv from the
glob_t structure after each
glob call; never save
the pointer across calls.
gl_offsfield says how many slots to leave. The blank slots contain null pointers.
globtries its best to keep on going despite any errors, reading whatever directories it can.
You can exercise even more control than this by specifying an
error-handler function errfunc when you call
errfunc is not a null pointer, then
glob doesn't give up
right away when it can't read a directory; instead, it calls
errfunc with two arguments, like this:
(*errfunc) (filename, error-code)
The argument filename is the name of the directory that
glob couldn't open or couldn't read, and error-code is the
errno value that was reported to
If the error handler function returns nonzero, then
glob gives up
right away. Otherwise, it continues.
globreturns that there were no matches.)
If you use
GLOB_NOESCAPE, then ‘\’ is an ordinary character.
glob does its work by calling the function
repeatedly. It handles the flag
GLOB_NOESCAPE by turning on the
FNM_NOESCAPE flag in calls to
