Detailed Description¶
This is a collection base64 encoding/decoding functions used in Wget2.Function Documentation¶
bool wget_base64_is_string (const char * src)¶
Parameters:Returns:
Checks whether src is a base64 string. Returns 0 if src is NULL.
size_t wget_base64_decode (char * dst, const char * src, size_t n)¶
Parameters:src Base64 string to be decoded
n Length of src
Returns:
Decodes n bytes of the base64 string src. The decoded bytes are written into dst and are 0-terminated.
The size of dst has to be at minimum ((n + 3) / 4) * 3 + 1 bytes.
char* wget_base64_decode_alloc (const char * src, size_t n, size_t * outlen)¶
Parameters:n Length of src
outlen Length of returned string, may be NULL.
Returns:
Decodes n bytes of the base64 string src. The decoded bytes are returned in an allocated buffer.
You should free() the returned string when not needed any more.
size_t wget_base64_encode (char * dst, const char * src, size_t n)¶
Parameters:src Input buffer
n Number of bytes to be encoded
Returns:
Encodes n bytes from src into a base64 string. The encoded string is written into dst (0-terminated).
The length of dst has to be at minimum ((n + 2) / 3) * 4 + 1 bytes.
char* wget_base64_encode_alloc (const char * src, size_t n)¶
Parameters:n Number of bytes to be encoded
Returns:
Encodes n bytes from input buffer src. The encoded string is returned in an allocated buffer.
You should free() the returned string when not needed any more.
char* wget_base64_encode_vprintf_alloc (const char * fmt, va_list args)¶
Parameters:args Argument list
Returns:
Encodes the string constructed by fmt and args. The encoded string is returned in an allocated buffer.
You should free() the returned string when not needed any more.
char* wget_base64_encode_printf_alloc (const char * fmt, ...)¶
Parameters:... Argument list
Returns:
Encodes the string constructed by fmt and the arguments. The encoded string is returned in an allocated buffer.
You should free() the returned string when not needed any more.
