g-variant-is-signature (string)

string -- a normal C nul-terminated string

True if string is a D-Bus type signature.

Determines if a given string is a valid D-Bus type signature. You should ensure that a string is a valid D-Bus type signature before passing it to the function g-variant-new-signature.

D-Bus type signatures consist of zero or more definite g-variant-type strings in sequence.
