## Function Documentation

## SoapySDR_free()

SOAPY_SDR_API void SoapySDR_free | ( | void * | ptr | ) |

Free a pointer allocated by SoapySDR. For most platforms this is a simple call around free()

## SoapySDRArgInfo_clear()

SOAPY_SDR_API void SoapySDRArgInfo_clear | ( | SoapySDRArgInfo * | info | ) |

Clear the contents of a argument info structure. This frees all the underlying memory and clears the members.

## SoapySDRArgInfoList_clear()

SOAPY_SDR_API void SoapySDRArgInfoList_clear | ( | SoapySDRArgInfo * | info,
|  | const size_t | length )

Clear a list of argument info structures. This frees all the underlying memory and clears the members.

## SoapySDRKwargs_clear()

SOAPY_SDR_API void SoapySDRKwargs_clear | ( | SoapySDRKwargs * | args | ) |

Clear the contents of a kwargs structure. This frees all the underlying memory and clears the members.

## SoapySDRKwargs_fromString()

SOAPY_SDR_API SoapySDRKwargs SoapySDRKwargs_fromString | ( | const char * | markup | ) |

Convert a markup string to a key-value map. The markup format is: "key0=value0, key1=value1"

## SoapySDRKwargs_get()

SOAPY_SDR_API const char * SoapySDRKwargs_get | ( | const SoapySDRKwargs * | args,
|  | const char * | key )

Get a value given a key in a kwargs structure.

Returns
  the string or NULL if not found

## SoapySDRKwargs_set()

SOAPY_SDR_API int SoapySDRKwargs_set | ( | SoapySDRKwargs * | args,
|  | const char * | key,
|  | const char * | val )

Set a key/value pair in a kwargs structure.

Postcondition
  If the key exists, the existing entry will be modified; otherwise a new entry will be appended to args. On error, the elements of args will not be modified, and args is guaranteed to be in a good state.

Returns
  0 for success, otherwise allocation error

## SoapySDRKwargs_toString()

SOAPY_SDR_API char * SoapySDRKwargs_toString | ( | const SoapySDRKwargs * | args | ) |

Convert a key-value map to a markup string. The markup format is: "key0=value0, key1=value1"

## SoapySDRKwargsList_clear()

SOAPY_SDR_API void SoapySDRKwargsList_clear | ( | SoapySDRKwargs * | args,
|  | const size_t | length )

Clear a list of kwargs structures. This frees all the underlying memory and clears the members.

## SoapySDRStrings_clear()

SOAPY_SDR_API void SoapySDRStrings_clear | ( | char *** | elems,
|  | const size_t | length )

Clear the contents of a list of string Convenience call to deal with results that return a string list.
