Function
GLibascii_strtoll
since: 2.12
Declaration [src]
gint64
g_ascii_strtoll (
const gchar* nptr,
gchar** endptr,
guint base
)
Description [src]
Converts a string to a gint64 value.
This function behaves like the standard strtoll() function
does in the C locale. It does this without actually
changing the current locale, since that would not be thread-safe.
This function is typically used when reading configuration
files or other non-user input that should be locale independent.
To handle input from the user you should normally use the
locale-sensitive system strtoll() function.
If the correct value would cause overflow, G_MAXINT64 or
G_MININT64 is returned, and ERANGE is stored in errno.
If the base is outside the valid range, zero is returned, and
EINVAL is stored in errno. If the
string conversion fails, zero is returned, and endptr returns nptr
(if endptr is non-NULL).
Available since: 2.12
Parameters
nptr-
Type:
const gchar*The string to convert to a numeric value.
The data is owned by the caller of the function. The value is a NUL terminated UTF-8 string. endptr-
Type:
gchar**If non-
NULL, it returns the character after the last character used in the conversion.The argument will be set by the function. The argument can be NULL.The returned data is owned by the function. The value is a NUL terminated UTF-8 string. base-
Type:
guintTo be used for the conversion, 2..36 or 0.
