Returns
  `SOAP_OK` or a `soap_status` error code

Parameters

  soap | `soap` context
  string | string to convert

Copy a string (ASCII or UTF-8) to a new string while converting and validating the string contents.

This function copies the specified string to a new string allocated in managed memory. The specified string is validated against the `minlen` and `maxlen` constraints and against the `pattern` XSD regex when non-NULL and when the `soap::fsvalidate` callback is assigned to perform this check. The minimum and maximum length constraints are 0 and `soap::maxlength`, respectively, when `minlen` or `maxlen` are specified as negative values. The string length verification takes UTF-8 multi-byte encoding into account when the `SOAP_C_UTFSTRING` mode flag is enabled. The `flag` parameter controls the conversion as follows: 0 = no conversion, 4 = collapse white space and normalize white space with blanks, 5 = collapse white space. Returns `SOAP_OK` or a `soap_status` error code.

Returns

Copy a string (ASCII or UTF-8) to a new wide string while converting and validating the string contents.

This function copies the specified string to a new wide string allocated in managed memory. When the `SOAP_C_UTFSTRING` mode flag is enabled the specified string should contain UTF-8 contents or ASCII otherwise. The specified string is validated against the `minlen` and `maxlen` constraints and against the `pattern` XSD regex when non-NULL and when the `soap::fsvalidate` callback is assigned to perform this check. The minimum and maximum length constraints are 0 and `soap::maxlength`, respectively, when `minlen` or `maxlen` are specified as negative values. The `flag` parameter controls the conversion as follows: 0 = no conversion, 4 = collapse white space and normalize white space with blanks, 5 = collapse white space. Returns `SOAP_OK` or a `soap_status` error code.

Returns
  `SOAP_OK` or a `soap_status` error code

  string | string to convert
  value | pointer to a variable to assign the new string to
  flag | controls conversion (0, 4 or 5)
  minlen | minimum string length constraint, when non-negative
  maxlen | maximum string length constraint, when non-negative
