SYNOPSIS¶

size_t * datalen

on input, maximum size of output buffer, on output, actual size of output buffer.

DESCRIPTION¶

Extract data stored in a ASN.1 field into a fixed size buffer allocated by caller.

Note that since it is difficult to predict the length of the field, it is often better to use shishi_asn1_read() instead.
