Yes, you are missing something. What you're missing is that this
function
is made by preprocessor magic. Look for these bits of code:
#define IMPLEMENT_PEM_write_cb_fp(name, type, str, asn1) \
int PEM_write_##name(FILE *fp, type *x, const EVP_CIPHER *enc, \
unsigned char *kstr, int klen, pem_password_cb *cb, \
void *u) \
{ \
return(PEM_ASN1_write((int (*)())i2d_##asn1,str,fp, \
(char *)x,enc,kstr,klen,cb,u)); \
}
#endif
#define DECLARE_PEM_write(name, type) \
DECLARE_PEM_write_bio(name, type) \
DECLARE_PEM_write_fp(name, type)
#define DECLARE_PEM_rw(name, type) \
DECLARE_PEM_read(name, type) \
DECLARE_PEM_write(name, type)
DECLARE_PEM_rw(DSA_PUBKEY, DSA)
