isListType, isTListType, isMListType

Check if it is a list, mlist, tlist variable.

Syntax

int isListType(void* _pvCtx, int* _piAddress)
int isNamedListType(void* _pvCtx, const char* _pstName)
int isTListType(void* _pvCtx, int* _piAddress)
int isNamedTListType(void* _pvCtx, const char* _pstName)
int isMListType(void* _pvCtx, int* _piAddress)
int isNamedMListType(void* _pvCtx, const char* _pstName)

Arguments

_pvCtx

Scilab environment pointer, pass in "pvApiCtx" provided by api_scilab.h.

_piAddress

Position in the Scilab memory where you want to put the variable.

_pstName

Name of the variable for "named" functions.

Return value

1 if variable is a list type, otherwise 0
