man shishi_asn1_read_inline (3): API function

SYNOPSIS

#include <shishi.h>

int shishi_asn1_read_inline(Shishi * handle, Shishi_asn1 node, const char * field, char * data, size_t * datalen);

ARGUMENTS

Shishi * handle: shishi handle as allocated by shishi_init().
Shishi_asn1 node: ASN.1 variable to read field from.
const char * field: name of field in node to read.
char * data: pre-allocated output buffer that will hold ASN.1 field data.
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.

RETURN VALUE

Returns SHISHI_OK if successful, SHISHI_ASN1_NO_ELEMENT if the element do not exist, SHISHI_ASN1_NO_VALUE if the field has no value, ot SHISHI_ASN1_ERROR otherwise.
