Summary

Declaration

Definition

from base64.h:45

int mbedtls_base64_encode(unsigned char *dst, size_t dlen, size_t *olen, const unsigned char *src, size_t slen);

Implemented in base64.c:61

Arguments

Argument

Declared as

Description

dst

unsigned char *

destination buffer

dlen

size_t

size of the destination buffer

olen

size_t *

number of bytes written

src

const unsigned char *

source buffer

slen

size_t

amount of data to be encoded

Return value

0 if successful, or MBEDTLS_ERR_BASE64_BUFFER_TOO_SMALL. *olen is always updated to reflect the amount of data that has (or would have) been written. If that length cannot be represented, then no data is written to the buffer and *olen is set to the maximum length representable as a size_t.

Notes

Call this function with dlen = 0 to obtain the required buffer size in *olen
