Summary

Declaration

Definition

from base64.h:81

int mbedtls_base64_decode( unsigned char *dst, size_t dlen, size_t *olen, const unsigned char *src, size_t slen );

Implemented in base64.c:144

Arguments

Argument

Description

dst

destination buffer (can be NULL for checking size)

dlen

size of the destination buffer

olen

number of bytes written

src

source buffer

slen

amount of data to be decoded

Return value

0 if successful, MBEDTLS_ERR_BASE64_BUFFER_TOO_SMALL, or MBEDTLS_ERR_BASE64_INVALID_CHARACTER if the input data is not correct. *olen is always updated to reflect the amount of data that has (or would have) been written.

Notes

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