validate
Description:
public bool validate (ssize_t max_len = -1, out char* end = null)
Validates UTF-8 encoded text.
str is the text to validate; if str is nul-terminated, then max_len can be -1, otherwise max_len
should be the number of bytes to validate. If end is non-null, then the end of the valid
range will be stored there (i.e. the start of the first invalid character if some bytes were invalid, or the end of the text being validated
otherwise).
Note that validate returns false if max_len is positive and any of
the max_len bytes are nul.
Returns true if all of str was valid. Many GLib and GTK routines require valid UTF-8 as input;
so data read from a file or the network should be checked with validate before doing anything else with it.
Parameters:
| max_len |
max bytes to validate, or -1 to go until NUL |
| end |
return location for end of valid data |
| str |
a pointer to character data |
Returns:
|
true if the text was valid UTF-8 |
