ssGetStringDataTypeMaxLength

Get maximum length of string data type

Syntax

size_t ssGetStringDataTypeMaxLength(SimStruct *S,int dataType)

Arguments

S: SimStruct representing an S-Function block.
dataType: 数据类型的ID。

Returns

A value of typesize_T, indicating the maximum length of the string.
0, if the string has no maximum length.

Description

ssGetStringDataTypeMaxLengthdetermines the maximum length (size_t) of a string. The string has no maximum length ifssGetStringDataTypeMaxLengthis0.

Limitations

Non-inlined S-functions that contain string SimStruct functions do not run with rapid accelerator mode.

Languages

C, C++

Example

This example gets the maximum length of a string.

... { if(ssGetStringDataTypeMaxLength(S, ssGetInputPortDataType(S, 0)) == 0) ssSetOutputPortDataType(S, 0, ssRegisterStringDataType(S, 0)); else ssSetOutputPortDataType(S, 0, ssRegisterStringDataType(S, ssGetStringDataTypeMaxLength(S, ssGetInputPortDataType(S, 0)) + mxGetN(INSSTR))); } ...
