 .Sh NAME
-.Nm index
-.Nd locate character in string
+.Nm imaxabs
+.Nd integer absolute value function
 .Sh SYNOPSIS
-.Fd #include <string.h>
-.Ft char *
-.Fn index "const char *s" "int c"
+.Fd #include <inttypes.h>
+.Ft intmax_t
+.Fn imaxabs "intmax_t j"
 .Sh DESCRIPTION
 The
-.Fn index
-function
-locates the first character matching
-.Fa c
-(converted to a
-.Em char )
-in the null-terminated string
-.Fa s .
+.Fn imaxabs
+function computes the absolute value of the intmax_t variable
+.Fa j .
 .Sh RETURN VALUES
-The character
-.Fa c
-is returned if it is found; otherwise
-.Dv NULL
-is returned.
-If
-.Fa c
-is '\e0',
-.Fn index
-locates the terminating '\e0'.
+The
+.Fn imaxabs
+function returns the absolute value.
