seq_open - initialize sequential file SYNOPSIS
int seq_open(struct file * file, const struct seq_operations * op); ARGUMENTS
file file we initialize op method table describing the sequence DESCRIPTION
seq_open sets file, associating it with a sequence described by op. op->start sets the iterator up and returns the first element of sequence. op->stop shuts it down. op->next returns the next element of sequence. op->show prints element into the buffer. In case of error ->start and ->next return ERR_PTR(error). In the end of sequence they return NULL. ->show returns 0 in case of success and negative number in case of error. Returning SEQ_SKIP means "discard this element and move on". COPYRIGHT

asn1_der_decoding_startEnd - API function SYNOPSIS
#include <libtasn1.h> int asn1_der_decoding_startEnd(asn1_node element, const void * ider, int len, const char * name_element, int * start, int * end); ARGUMENTS
asn1_node element pointer to an ASN1 element const void * ider vector that contains the DER encoding. int len number of bytes of *ider: ider[0]..ider[len-1] const char * name_element an element of NAME structure. int * start the position of the first byte of NAME_ELEMENT decoding (ider[*start]) int * end the position of the last byte of NAME_ELEMENT decoding (ider[*end]) DESCRIPTION
Find the start and end point of an element in a DER encoding string. I mean that if you have a der encoding and you have already used the function asn1_der_decoding() to fill a structure, it may happen that you want to find the piece of string concerning an element of the structure. One example is the sequence "tbsCertificate" inside an X509 certificate. RETURNS
ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is asn1_node EMPTY or name_element is not a valid element, ASN1_TAG_ERROR or ASN1_DER_ERROR if the der encoding doesn't match the structure ELEMENT. COPYRIGHT
