Parse a single directive from a pack or unpack format string.
variant | (in) pack or unpack |
format | (in, out) the start of the next directive to parse on calling, and advanced beyond the parsed directive on return, or as much of it as was consumed until an error was encountered |
format_end | (in) the end of the format string |
type | (out) the type of the directive |
signed_type | (out) whether the value is signed |
endian | (out) the endianness of the value |
size | (out) the size of the value |
length_type | (out) what kind of length is specified |
length | (out) the length of the directive |
encoding | (in, out) takes the current encoding of the string which would result from parsing the whole format string, and returns a possibly changed directive - the encoding should be PM_PACK_ENCODING_START when pm_pack_parse is called for the first directive in a format string |
