CGo Test

A repo to experiment with C and Go interop. Heavily uses CGo.

Memory Allocation Test

Currently the only supported test. Allocates memory using calloc or Go assigment for a specified number of iterations. Note: Go formats Durations intelligently, so it will change the units as appropriate. The C Malloc results will always be in ms.

neel@neel-UX305FA:~/go/src/cgo-test$ ./cgo-test 
2020/06/07 09:15:23 C malloc took 124.793000ms
2020/06/07 09:15:24 cGoMalloc took 316.583381ms
2020/06/07 09:15:24 goAssign took 240.907226ms

The number of iterations can be specified using a command line flag.
