- Synopsis:
- $fexist(<file>)
-
- Technical:
- This function tests for the existence of the given file. The function
- permits tilde-expansion.
-
- Practical:
- This function is used when you want to see if a particular file exists.
- This could be useful to make sure a file is present before trying to
- load it.
-
- Returns:
- -1 error, unable to access file
- 1 file exists and client has read permission
-
- Examples:
- $fexist(/etc/passwd) probably will return 1
- $fexist(~/.ircrc) probably will return 1 too
- $fexist(fake_file) returns -1
-
- See Also:
- open(6)
-
- Other Notes:
- This function never returns 0. This is worth noting, because the natural
- tendency will be to check for the return value's existence, not its
- actual value (meaning it always returns "true", as far as the client's
- string parser is concerned). This was done intentionally to match the
- return values of $fsize().
