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 variable 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 generally be freed before calling this function to avoid memory leaks. Note that there is an equivalent macro (), which performs this function with no data verification or function call overhead. Use the macro version to maximize performance where the validity of new_num_fields is guaranteed by other means.

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