|

| 2 | The header <errno.h> defines several macros, all relating to the reporting of
|
|---|
| 3 | error conditions.
|
|---|
| 4 |
|
|---|
| 5 | The ISO/IEC 9899 specification requires that these be macros.
|
|---|
| 6 |
|
|---|
| 7 | The macros expand to integral constant expressions
|
|---|
| 8 | with distinct nonzero values, suitable for use in #if preprocessing
|
|---|
| 9 | directives; the variable errno which expands to a modifiable lvalue that has type int,
|
|---|
| 10 | the value of which is set to a positive error number by several library
|
|---|
| 11 | functions; and the variable EFIerrno which is an extension allowing the return status
|
|---|
| 12 | of the underlying UEFI functions to be returned.
|
|---|
| 13 |
|
|---|
| 14 | The value of errno and EFIerrno is zero at program startup. On program startup, errno
|
|---|
| 15 | is initialized to zero but is never set to zero by
|
|---|
| 16 | any library function. The value of errno may be set to a non-zero value by
|
|---|
| 17 | a library function call whether or not there is an error, provided the use
|
|---|
| 18 | of errno is not documented in the description of the function in
|
|---|
| 19 | the governing standard: ISO/IEC 9899:1990 with Amendment 1 or ISO/IEC 9899:199409.
|
|---|
| 20 |
|
|---|
| 21 | EFIerrno, like errno, should only be checked if it is known that the preceeding function call
|
|---|
| 22 | called a UEFI function. Functions in which UEFI functions are called dependent upon context
|
|---|
| 23 | or parameter values should guarantee that EFIerrno is set to zero by default, or to the status
|
|---|
| 24 | value returned by any UEFI functions which are called.
|
|---|
| 25 |
|
|---|
| 26 | All macro definitions in this list must begin with the letter 'E'
|
|---|
| 27 | and be followed by a digit or an uppercase letter.
