Message 216425 - Python tracker
In numpy, I found the two following functions: /*NUMPY_API * Allocates memory for array data. */ void* PyDataMem_NEW(size_t size); /*NUMPY_API * Allocates zeroed memory for array data. */ void* PyDataMem_NEW_ZEROED(size_t size, size_t elsize); So it looks like it needs two size_t parameters. Prototype of the C function calloc(): void *calloc(size_t nmemb, size_t size); I agree that it's better to provide the same prototype than calloc().
