How do you expect it to give you "Inbox" as an integer? If you will
settle for a pointer to a string, since what you are really doing is
parsing a string into tokens, strtok (which is messy, non-reentrant and
generally deprecated, but is ANSII C and therefor portable) or strtok_r
or strsep. To move the strings into local variables, you could use
str[n]cpy. All of these seem to destroy the input data by substituting
\0 for each delimiter as it is found.

char name[57];
char data[] = "0 Inbox FOLD0000.frm"
char *line = data;
foo = strsep(&line, " "); /* foo points to "0" */
foo = strsep(&line, " "); /* now foo points to "Inbox" */
strcpy(name, foo);

Number of letters? Current letter number? Don't know. :-)
