NAME

6       oath_base32_encode - API function
7

SYNOPSIS

9       #include <oath.h>
10
11       int  oath_base32_encode(const  char  *  in,  size_t inlen, char ** out,
12       size_t * outlen);
13

ARGUMENTS

15       const char * in
16                   input string with binary data of length inlen
17
18       size_t inlen
19                   length of input data in
20
21       char ** out pointer to newly allocated output string of length  outlen,
22                   or NULL
23
24       size_t * outlen
25                   pointer to output variable holding length of out, or NULL
26

DESCRIPTION

28       Encode binary data into a string with base32 data.
29
30       The  in  parameter  should  contain inlen bytes of data to encode.  The
31       function allocates a new string in *out to hold the encoded  data,  and
32       sets  *outlen  to  the  length  of the data.  The output string *out is
33       zero-terminated (ASCII NUL), but the NUL is not counted in *outlen.
34
35       If out is NULL, then *outlen will be set to what would  have  been  the
36       length of *out on successful encoding.
37
38       If  the  caller  is  not interested in knowing the length of the output
39       data out, then outlen may be set to NULL.
40
41       It is permitted but useless to have both out and outlen NULL.
42

RETURNS

44       On success OATH_OK (zero) is returned, OATH_BASE32_OVERFLOW is returned
45       if the output would be too large to store, and OATH_MALLOC_ERROR is re‐
46       turned on memory allocation errors.
