Function

GLibascii_digit_value

Declaration [src]

gint
g_ascii_digit_value(
gcharc
)

Description [src]

Determines the numeric value of a character as a decimal digit. If the character is not a decimal digit according to g_ascii_isdigit(), -1 is returned.

Differs from g_unichar_digit_value() because it takes a char, so there’s no worry about sign extension if characters are signed.

Parameters

c

Type: gchar

An ASCII character.

Return value

Type: gint

The numerical value of c if it is a decimal digit, -1 otherwise.
