alloc_sqlda Function

Allocates a SQLDA with descriptors for numvar variables.

Syntax

struct sqlda * alloc_sqlda( unsigned numvar );

Parameters

numvar – The number of variable descriptors to allocate.

Returns

Pointer to a SQLDA if successful and returns the null pointer if there is not enough memory available.

Remarks

Allocates a SQLDA with descriptors for numvar variables. The sqln field of the SQLDA is initialized to numvar. Space is allocated for the indicator variables, the indicator pointers are set to point to this space, and the indicator value is initialized to zero. A null pointer is returned if memory cannot be allocated. It is recommended that you use this function instead of the alloc_sqlda_noind function.
