Hi all,
I discovered that calling the function
cl_int clgetplatformids (cl_uint num_entries, cl_platform_id *platforms, cl_uint *num_platforms) with the
platforms parameter set to NULL and the
num_entries different from zero I get a CL_INVALID_VALUE error return value. Follows an example of the code used:
cl_uint err, platformCount;
// get platform counter
err = clGetPlatformIDs (1, NULL, &platformCount);
if (err != CL_SUCCESS) {
printf("ERROR %s\n", getErrorString(err));
exit(err);
}
This should not happened because as defined from the standard: (
https://www.khronos.org/registry/cl/sdk/1.0/docs/man/xhtml/clgetplatformids.html)

Errors:
Returns CL_SUCCESS if the function is executed successfully. Otherwise it returns CL_INVALID_VALUE if
num_entries is equal to zero and platforms is not NULL, or if both
num_platforms and
platforms are NULL.

Is it wanted from Altera or is it a bug in the implementation? :confused:
p.s: If I use clGetPlatformIDs (0, NULL, &platformCount) works perfectly.
