Are you attempting to escape the "/" character?  Like "\/usr\/home\/foo"?
I don't think you need to do that.  Also, you can't "equate" a pointer to
an array to a string (presuming that "name" is an array).  You must do a
memberwise copy.  I suggest strcpy().

#include <stdio.h> 
#include <string.h> 
void 
main(void)  {

        FILE *fp; 
        char chaArray[45] = {'\0'}; 
        char chaTestString[80]; 

        strcpy(chaArray, "./test.c");  // your name="/usr/home/foo";
        printf("chaArray = \"%s\"\n", chaArray);  // Yes, I'm really here.
        fp = fopen((const char *) chaArray, "r");  // Hi, I will be your
                                                   // file pointer today.
        do {
                (void) fgets(chaTestString, 79, fp); 
                // cat /dev/codingflames > /dev/null | tee /dev/:-)
                printf("bytes read from %s:%s",
                       chaArray,
                       chaTestString); 
        } while (!feof(fp)); 
        fclose(fp);  
}
