DESCRIPTION
These functions convert to and fromASN1_INTEGER_get_int64() converts an
ASN1_INTEGER_get_uint64() is similar to ASN1_INTEGER_get_int64_t() except it converts to a uint64_t type and an error is returned if the passed integer is negative.
ASN1_INTEGER_get() also returns the value of a but it returns 0 if a is
ASN1_INTEGER_set_int64() sets the value of
ASN1_INTEGER_set_uint64() sets the value of
ASN1_INTEGER_set() sets the value of
BN_to_ASN1_INTEGER() converts
ASN1_INTEGER_to_BN() converts
ASN1_ENUMERATED_get_int64(), ASN1_ENUMERATED_set_int64(), ASN1_ENUMERATED_set(), BN_to_ASN1_ENUMERATED() and ASN1_ENUMERATED_to_BN() behave in an identical way to their
ASN1_ENUMERATED_get() returns the value of a in a similar way to ASN1_INTEGER_get() but it returns 0xffffffffL if the value of a will not fit in a long type. New applications should use ASN1_ENUMERATED_get_int64() instead.
NOTES
In general anBUGS
The ambiguous return values of ASN1_INTEGER_get() and ASN1_ENUMERATED_get() mean these functions should be avoided if possible. They are retained for compatibility. Normally the ambiguous return values are not legitimate values for the fields they represent.RETURN VALUES
ASN1_INTEGER_set_int64(), ASN1_INTEGER_set(), ASN1_ENUMERATED_set_int64() and ASN1_ENUMERATED_set() return 1 for success and 0 for failure. They will only fail if a memory allocation error occurs.ASN1_INTEGER_get_int64() and ASN1_ENUMERATED_get_int64() return 1 for success and 0 for failure. They will fail if the passed type is incorrect (this will only happen if there is a programming error) or if the value exceeds the range of an int64_t type.
BN_to_ASN1_INTEGER() and BN_to_ASN1_ENUMERATED() return an
ASN1_INTEGER_to_BN() and ASN1_ENUMERATED_to_BN() return a
