dsv_line_set_num_fields(3)

LIBRARY
#include <xtend/dsv.h>
-lxtend

SYNOPSIS

int     dsv_line_set_num_fields(dsv_line_t *dsv_line_ptr, size_t new_num_fields)

ARGUMENTS
dsv_line_ptr    Pointer to the structure to set
new_num_fields  The new value for num_fields

DESCRIPTION
Mutator for num_fields member in a dsv_line_t structure. Use this function to set num_fields in a dsv_line_t object from non-member functions. This function performs a direct assignment for scalar or pointer structure members. If num_fields is a pointer, data previously pointed to should be freed before calling this function to avoid memory leaks.

RETURN VALUES
BL_DSV_DATA_OK if the new value is acceptable and assigned BL_DSV_DATA_OUT_OF_RANGE otherwise

EXAMPLES
dsv_line_t      dsv_line;
size_t          new_num_fields;
if ( dsv_line_set_num_fields(&dsv_line, new_num_fields)
        == BL_DSV_DATA_OK )
{
}
