gsk_read_data

Processes a PKCS #7 Data message.

Format

#include <gskcms.h>

gsk_status gsk_read_data_msg (
                              gsk_buffer *        stream,
                              gsk_buffer *        data)

Parameters

stream: Specifies the ASN.1 DER-encoded stream to be processed.
data: Returns the application data. The application should call the gsk_free_buffer() routine to release the data when it is no longer needed.

Results

The function return value will be 0 if no error is detected. Otherwise, it will be one of the return codes listed in the gskcms.h include file. These are some possible errors:

[CMSERR_CONTENT_NOT_SUPPORTED]: The message content type is not Data.
[CMSERR_NO_MEMORY]: Insufficient storage is available.

Usage

The gsk_read_data_msg() routine processes a PKCS #7 (Cryptographic Message Syntax) Data message created by the gsk_make_data_msg() routine and returns the application data. The message content type must be Data.

Calling the gsk_read_data_msg() routine is equivalent to calling the gsk_read_content_msg() routine followed by the gsk_read_data_content() routine.
