[Pyrex] using C char array problem

[Eric Colleu]

Hi,

I have a problem with pyrex array management.
I define a type
ctypedef char machaine[10]
And I try to pass an array of this type to a C function with no success.
Below is my C code and pyrex code.
Please help me or I'm gonna be crazy...

Thanks

Eric Colleu

void testDeTableauDeString(machaine *montableau, int nbelt)
{
         int i, j;
         printf("testDeTableauDeString %d\n", nbelt);
         for(i=0;i<nbelt;i++) {
                 printf("%d ", i);
                 for(j=0;j<10;j++) {
                         printf("%2.2x ", montableau[i][j]);
                 }
                 printf("\n-- %s --\n", montableau[i]);
