accessing data from file path with"space" on windows - c

Question

I'm facing a weird problem on windows
I'm using a library called STDCL which runs pretty well on linux,but on windows there is an error if the output .exe file path got "spaces"
example:
c:\my file\my file.exe //won't work
c:\my_file\my file.exe //will work
c:\my file\my file.exe //won't work
// and it is accessing data from dll(any where) containing STDCL library
c:\my_file\my file.exe //will work
// and it is accessing data from dll(any where) containing STDCL library
I got the source code to compile the library
or is there an easier way to force accepting the path of the .exe inside my .dll
edit: sample code
/* hello_stdcl.c */
#include <stdio.h>
#include <stdcl.h>
int main()
{
stdcl_init(); // this is only necessary for Windows
cl_uint n = 64;
#if(1)
/* use default contexts, if no GPU use CPU */
CLCONTEXT* cp = (stdgpu)? stdgpu : stdcpu;
unsigned int devnum = 0;
void* clh = clopen(cp,"matvecmult.cl",CLLD_NOW);
cl_kernel krn = clsym(cp,clh,"matvecmult_kern",0);
/* allocate OpenCL device-sharable memory */
cl_float* aa = (float*)clmalloc(cp,n*n*sizeof(cl_float),0);
cl_float* b = (float*)clmalloc(cp,n*sizeof(cl_float),0);
cl_float* c = (float*)clmalloc(cp,n*sizeof(cl_float),0);
clndrange_t ndr = clndrange_init1d( 0, n, 64);
/* initialize vectors a[] and b[], zero c[] */
int i,j;
for(i=0;i<n;i++) for(j=0;j<n;j++) aa[i*n+j] = 1.1f*i*j;
for(i=0;i<n;i++) b[i] = 2.2f*i;
for(i=0;i<n;i++) c[i] = 0.0f;
/* define the computational domain and workgroup size */
//clndrange_t ndr = clndrange_init1d( 0, n, 64);
/* non-blocking sync vectors a and b to device memory (copy to GPU)*/
clmsync(cp,devnum,aa,CL_MEM_DEVICE|CL_EVENT_NOWAIT);
clmsync(cp,devnum,b,CL_MEM_DEVICE|CL_EVENT_NOWAIT);
/* set the kernel arguments */
clarg_set(cp,krn,0,n);
clarg_set_global(cp,krn,1,aa);
clarg_set_global(cp,krn,2,b);
clarg_set_global(cp,krn,3,c);
/* non-blocking fork of the OpenCL kernel to execute on the GPU */
clfork(cp,devnum,krn,&ndr,CL_EVENT_NOWAIT);
/* non-blocking sync vector c to host memory (copy back to host) */
clmsync(cp,0,c,CL_MEM_HOST|CL_EVENT_NOWAIT);
/* force execution of operations in command queue (non-blocking call) */
clflush(cp,devnum,0);
/* block on completion of operations in command queue */
clwait(cp,devnum,CL_ALL_EVENT);
for(i=0;i<n;i++) printf("%d %f %f\n",i,b[i],c[i]);
clfree(aa);
clfree(b);
clfree(c);
clclose(cp,clh);
#endif
system("pause");
}
edit 2:
when I compile the code above ...take the result .exe file and put it in a path without spaces (short path) it works
if I put it in a path with spaces ...it simply crashes and when I debugged it was like memory issue (so it crashes with long path)
when I contacted the library creator he told me:
"windows getcwd() call returns an unusable path with spaces"
as I told before this library works fine on Linux,what may be the solution for this on Windows
system: win7 64 bit

Answer 1

Use quates for the binary name/path as "my file.exe"
