fprintf internally supports print character array in hex?

Show all headers | View raw

Consider this code snippet:

char buffer[128];
int  i,len;
   /* code that puts data in buffer and sets len */
for(i=0;i<len;i++){fprintf(stdout,"%x",buffer[i]);}

With the newer formatting options in fprintf (like "*" and "%m") can the 
for loop now be replaced with a single fprintf like:

    fprintf(stdout,"%????x",buffer,len);

where ???? is some combination of the newer format options.

Thanks,

David Mathog
