:mrdocs:

This component‐private utility `struct` provides a namespace for a suite of functions used by `BerUtil` to implement BER length quantity encoding and decoding.

== Synopsis

Declared in `<balber_berutil.h>`

== Type Aliases

[cols="1,4"]

| Name| Description
| xref:BloombergLP/balber/BerUtil_LengthImpUtil/Constants.adoc[`Constants`] 
| `Constants` is an alias to a namespace for a suite of general‐purpose constants that occur when encoding or decoding BER data.
| xref:BloombergLP/balber/BerUtil_LengthImpUtil/RawIntegerUtil.adoc[`RawIntegerUtil`] 
| `RawIntegerUtil` is an alias to a namespace for a suite of functions used to implement integer encoding.

== Static Member Functions

[cols="1,4"]
|===
| Name| Description
| xref:BloombergLP/balber/BerUtil_LengthImpUtil/getEndOfContentOctets.adoc[`getEndOfContentOctets`] 
| Decode the "end‐of‐content" octets (two consecutive zero‐octets) from the specified `streamBuf` and add the number of bytes consumed (which is always 2) to the specified `accumNumBytesConsumed`. Return 0 on success, and a non‐zero value otherwise.
| xref:BloombergLP/balber/BerUtil_LengthImpUtil/getLength.adoc[`getLength`] 
| Decode the length octets from the specified `streamBuf` and load the result to the specified `result`. If the length is indefinite (i.e., contents will be terminated by "end‐of‐content" octets) then `result` will be set to `k_INDEFINITE_LENGTH`. Add the number of bytes consumed to the specified `accumNumBytesConsumed`. Return 0 on success, and a non‐zero value otherwise.
| xref:BloombergLP/balber/BerUtil_LengthImpUtil/putEndOfContentOctets.adoc[`putEndOfContentOctets`] 
| Encode the identifier octets for the specified `tagClass`, `tagType` and `tagNumber` to the specified `streamBuf`. Return 0 on success, and a non‐zero value otherwise.
| xref:BloombergLP/balber/BerUtil_LengthImpUtil/putIndefiniteLengthOctet.adoc[`putIndefiniteLengthOctet`] 
| Encode the "indefinite‐length" octet onto the specified `streamBuf`. This octet signifies that the length of the contents is indefinite (i.e., contents will be terminated by end of content octets). Return 0 on success, and a non‐zero value otherwise.
| xref:BloombergLP/balber/BerUtil_LengthImpUtil/putLength.adoc[`putLength`] 
| Encode the specified `length` length octets to the specified `streamBuf`. Return 0 on success, and a non‐zero value otherwise. The behavior is undefined unless `0 <= length`.
