def perror(name : str, error_code : int): ## TODO call libgamma_perror
'''
Prints an error to stderr in a `perror` fashion,
however this function will not translate the `libgamma`
errors into human-readable strings, it will simply
print the name of the error. If the value `error_code`
is the value of `LIBGAMMA_ERRNO_SET`, `perror` will be
used to print the current error stored in `errno`.
If `error_code` is non-negative (an `errno` value`), that
value will be stored in `errno` and `perror` will be
used to print it. Additionally, if the `error_code` is
the value of `LIBGAMMA_DEVICE_REQUIRE_GROUP` the
required group will be printed with its numerical value
and, if known, its name.
@param name The text to add at the beginning.
@param value The error code, may be an `errno` value.
'''
pass
def name_of_error(value : int) -> str: ## TODO call libgamma_name_of_error
'''
Returns the name of the definition associated with a `libgamma` error code.
@param value The error code.
@return The name of the definition associated with the error code,
`None` if the error code does not exist. The return string
should not be `free`:d.
'''
pass
def value_of_error(name : str) -> int: ## TODO call libgamma_value_of_error
'''
Return the value of a `libgamma` error definition refered to by name.
@param name The name of the definition associated with the error code.
@return The error code, zero if the name does is `None`
or does not refer to a `libgamma` error.
