mmr_error_info

Synopsis:

#include <mm/renderer/types.h>

typedef struct mmr_error_info {
    uint32_t error_code;
    char extra_type[20];
    int64_t extra_value;
    char extra_text[256];
} mmr_error_info_t;

Data:

uint32_t error_code: One of the mm_error_code_t constants.
char extra_type[20]);: A short string identifying the API or protocol that defines the meaning of extra_value, such as errno, http, or mmf
int64_t extra_value: An error number according to extra_type.
char extra_text[256]);: Free-form text describing the error. This may or may not have a format formally defined by a specification. For example, when extra_type is http, this field contains an HTTP server response string.

Library:

mmrndclient

Description:

The mmr_error_info_t structure type stores the error information generated by mm-renderer functions. Use the mmr_error_info() function to retrieve this information for a particular context and function call.

This multifield structure allows plugins to return protocol- or API-specific error information in addition to the MMR error code. The extra_type string is a tag that specifies how to interpret the extra_value and extra_text fields.

The values of extra_type currently supported and the associated contents of the other two fields are as follows:

`extra_type`	`extra_value`	`extra_text`
(empty string)	0	Usually empty, possibly some descriptive text
`errno`	An `errno` value	Usually the result of `strerror(extra_value)`, but possibly something more descriptive
`mmf`	One of the MMF error codes (not a valid `errno`)	Usually empty, but possibly something more descriptive
`http`	An HTTP response code	An HTTP server response
`libcurl`	A libcurl error code (but not CURLE_HTTP_RETURNED_ERROR)	The corresponding libcurl error message
