Detailed Description

Typedef Documentation

apu_err_t

typedef struct apu_err_t apu_err_t

This structure allows the underlying API error codes to be returned along with plain text error messages that explain to us mere mortals what really happened.

Function Documentation

apr_errprintf()

apu_err_t * apr_errprintf	(	apu_err_t *	result,
		apr_pool_t *	p,
		const char *	reason,
		int	rc,
		const char *	fmt,
			...
	)

Populate a apu_err_t structure with the given error, allocated from the given pool.

If the result parameter points at a NULL pointer, a apu_err_t structure will be allocated, otherwise the apu_err_t structure will be reused.

Parameters

result	If NULL, the apu_err_t structure is allocated and returned, otherwise the existing apu_err_t is used.
p	The pool to use.
reason	The reason string, may be NULL.
rc	The underlying result code.
fmt	The format of the string
...	The arguments to use while printing the data

Returns

The apu_err_t structure on success, NULL if out of memory.
