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