gboolean g_ascii_string_to_signed ( const gchar* str, guint base, gint64 min, gint64 max, gint64* out_num, GError** error )
A convenience function for converting a string to a signed number.
This function assumes that
str contains only a number of the given
base that is within inclusive bounds limited by
this is true, then the converted number is stored in
empty string is not a valid input. A string with leading or
trailing whitespace is also an invalid input.
base can be between 2 and 36 inclusive. Hexadecimal numbers must
not be prefixed with “0x” or “0X”. Such a problem does not exist
for octal numbers, since they were usually prefixed with a zero
which does not change the value of the parsed number.
Parsing failures result in an error with the
domain. If the input is invalid, the error code will be
G_NUMBER_PARSER_ERROR_INVALID. If the parsed number is out of
g_ascii_strtoll() if you have more complex needs such as
parsing a string which starts with a number, but then has other characters.

The data is owned by the caller of the function. The value is a NUL terminated UTF-8 string.
Base of a parsed number.
A lower bound (inclusive)
An upper bound (inclusive)
A return location for a number.
The argument will be set by the function. The argument can be
The return location for a recoverable error.
The argument can be
If the return location is not
NULL, then you must initialize it to a
The argument will be left initialized to
NULLby the function if there are no errors.
In case of error, the argument will be set to a newly allocated
GError; the caller will take ownership of the data, and be responsible for freeing it.
