from asn1.h:266

int mbedtls_asn1_get_bool(unsigned char **p, const unsigned char *end, int *val);

Implemented in asn1parse.c:80

Arguments

Argument

Description

On entry, \c *p points to the start of the ASN.1 element. On successful completion, \c *p points to the first byte beyond the ASN.1 element. On error, the value of \c *p is undefined.

end

End of data.

val

On success, the parsed value (\c 0 or \c 1).
