More Variable Manipulation Macros

The following macros can be used to get information from varinfo_t structures. Like the variable creation functions, these macros are defined in the file rpc_idl.h.

All of these macros accept a single argument v of varinfo_t type.

GetArrayData(v)

This macro returns a pointer to the array data described by the varinfo_t structure.

GetArrayDimensions(v)

This macro returns the dimensions of the array described by the varinfo_t structure. The dimensions are returned as long dimensions[].

GetArrayNumDims(v)

This macro returns the number of dimensions of the array.

GetVarByte(v)

This macro returns the value of a 1-byte, unsigned char variable.

GetVarComplex(v)

This macro returns the value (as a struct, not a pointer) of a complex variable.

GetVarDComplex(v)

This macro returns the value (as a struct, not a pointer) of a double-precision, complex variable.

GetVarDouble(v)

This macro returns the value of a double-precision, floating-point variable.

GetVarFloat(v)

This macro returns the value of a single-precision, floating point variable.

GetVarInt(v)

This macro returns the value of a 2-byte integer variable.

GetVarLong(v)

This macro returns the value of a 4-byte integer variable.

GetVarString(v)

This macro returns the value of a string variable (as a char*).

GetVarType(v)

This macro returns the type of the variable described by the varinfo_t structure. The type is returned as IDL_TYP_XXX as described under the documentation for the get_idl_variable function.

VarIsArray(v)

This macro returns non-zero if v is an array variable.
