errno question

I want to be able to print out the string which describes the error number returned

Note this is not the description returned by strerror, I want to get my hands on EXXXXX in string format.

If you want to print the error number, then you can print the value of errno. It already holds the error number!

  printf( "errno = %d, description: %s\n", errno, strerror(errno));

It's possible _only_ by defining your own array of strings like:

char *errno_str[]={"OK", "EPERM", "ENOENT", ... };

look to /usr/include/sys/errno.h for all possibilities.
Also there may be name collision where same integer have two names (like EWOULDBLOCK  == EAGAIN )
