|
|
// Purpose: To provide a common set of error codes
|
||
|
|
// Description: This provides a common set of error codes that all
|
||
|
|
// packages can agree on. It doesn't preclude them defining
|
||
|
|
// their own error return system, but this is a preferable
|
||
|
|
// system to use to help error support be as general as
|
||
|
|
// possible.
|
||
|
|
//
|
||
|
|
// We try and conform to the ANSI/POSIX error code format,
|
||
|
|
// namely starting with the character 'E'
|
||
|
|
//
|
||
|
|
// Usage: #include <cyg/error/codes.h>
|
||
|
|
//
|
||
|
|
// Example:
|
||
|
|
//
|
||
|
|
// err=myfun();
|
||
|
|
// if (err != ENOERR)
|
||
|
|
// {
|
||
|
|
// str=strerror(err);
|
||
|
|
// printf("myfun returned error: %s\n", str);
|
||
|
|
// }
|
||
|
|
// else ....
