Vl-unary-syscall-p

Recognize calls of a particular unary system function call.

Signature

(vl-unary-syscall-p name x) → *

Arguments

name — Name of the particular system call, e.g., $bits.
    Guard (stringp name).

x — Expression to test.
    Guard (vl-expr-p x).

For instance, to see if x is a call of $bits, you could write:

(vl-unary-syscall-p "$bits" x)
