Detailed Description

Typedef Documentation

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

apu_err_t __attribute__ ( (nonnull(2))  )
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.

resultIf NULL, the apu_err_t structure is allocated and returned, otherwise the existing apu_err_t is used.
pThe pool to use.
reasonThe reason string, may be NULL.
rcThe underlying result code.
fmtThe format of the string
...The arguments to use while printing the data
The apu_err_t structure on success, NULL if out of memory.
