Can't find definition of vmmin() in R package MASS

I am going through the isoMDS calculation in the MASS package. IsoMDS calls the c function VR_mds_dovm in src/MASS.c, then vmmin() is called at line 269 but I can't find the definition of that function.

I tried searching "vmmin" on the whole repo but the only result was the line where it is called. I tried googling "R MASS vmmin definition" but did not get any relevant results.

Since the function is not from MASS, it has to come from one of the linked libraries. Indeed, vmmin is a function from R's C API used for optimization; here the declaration and definition.
