char *strerror( char *str )
- prototype in string.h
- str should contain your customized error message to which a system
error message will be appended
- allows you to generate customized error messages, returning a
pointer to a null-terminated string containing an error message
- if str is NULL, the return value contains the most recently
generated system error message; this string is null-terminated
- if str is not NULL, the return value contains, a colon, a space,
the most recently generated system error message, and a newline;
with length of str being 94 characters or less
- this function generates the error string but does NOT print it
- for accurate error-handling, strerror should be called as soon
as a library routine generates an error return
