=head1 NAME

OSSL_CMP_STATUSINFO_new,
OSSL_CMP_snprint_PKIStatusInfo,
OSSL_CMP_CTX_snprint_PKIStatus
- function(s) for managing the CMP PKIStatus

=head1 SYNOPSIS

 #include <openssl/cmp.h>

 OSSL_CMP_PKISI *OSSL_CMP_STATUSINFO_new(int status, int fail_info,
                                         const char *text);
 char *OSSL_CMP_snprint_PKIStatusInfo(const OSSL_CMP_PKISI *statusInfo,
                                      char *buf, size_t bufsize);
 char *OSSL_CMP_CTX_snprint_PKIStatus(const OSSL_CMP_CTX *ctx, char *buf,
                                      size_t bufsize);

=head1 DESCRIPTION

This is the PKIStatus API for using CMP (Certificate Management Protocol) with
OpenSSL.

OSSL_CMP_STATUSINFO_new() creates a new PKIStatusInfo structure
and fills in the given values.
It sets the status field to I<status>,
copies I<text> (unless it is NULL) to statusString,
and interprets I<fail_info> as bit pattern for the failInfo field.

OSSL_CMP_snprint_PKIStatusInfo() places a human-readable string
representing the given statusInfo
in the given buffer, with the given maximal length.

OSSL_CMP_CTX_snprint_PKIStatus() places a human-readable string
representing the PKIStatusInfo components of the CMP context I<ctx>
in the given buffer, with the given maximal length.

=head1 NOTES

CMP is defined in RFC 9810.

=head1 RETURN VALUES

OSSL_CMP_STATUSINFO_new()
returns a pointer to the structure on success, or NULL on error.

OSSL_CMP_snprint_PKIStatusInfo() and
OSSL_CMP_CTX_snprint_PKIStatus()
return a copy of the buffer pointer containing the string or NULL on error.

=head1 HISTORY

The OpenSSL CMP support was added in OpenSSL 3.0.
