Name strerror - returns pointer to error message string
Usage char *strerror(char *str);
Prototype in string.h
Description strerror allows you to generate customized error
messages; it returns 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 str (your
customized error message), a colon, a space, the most recently
generated system error message, and a newline.
The length of str should be 94 characters or less.
strerror is different from perror in that it does not print
error messages.
For accurate error handling, strerror should be called as soon
as a library routine generates an error return.
Return value strerror returns a pointer to a constructed error
string. The error message string is constructed in a static
buffer that is over-written with each call to perror.
