scan_base64(3) Library Functions Manual scan_base64(3) NAME scan_base64 - decode base64 encoded data SYNTAX #include <libowfat/textcode.h> size_t scan_base64(const char *src,char *dest,size_t* destlen); DESCRIPTION scan_base64 decodes base64 encoded data from src into dest. It will stop when it encounters any non-valid input characters. It will then write the number of decoded bytes in dest into *destlen, and return the number of bytes decoded from src. Note that real world base64 encoded data is sometimes permitted to contain whitespace characters or new lines. This function will not allow those and return the decoded data until then. Many base64 variants demand padding in the last block. Some don't. This im- plementation will consume padding if it is there, but will not complain if it is not. dest can be NULL. destlen can be NULL. dest can be src. RETURN VALUE scan_base64 returns the number of bytes successfully scanned and processed from src. EXAMPLES scan_base64("Zm5vcmQ=",buf,&i) -> return 8, i=5, buf="fnord" SEE ALSO scan_base64url(3), scan_xlong(3), scan_8long(3), fmt_ulong(3) scan_base64(3)
