xt_ff_set_buff_index(3)

LIBRARY
#include <xtend/fast-file.h>
-lxtend

SYNOPSIS
int     xt_ff_set_buff_index(xt_ff_t *xt_ff_ptr, ssize_t new_buff_index)

ARGUMENTS
xt_ff_ptr    Pointer to the structure to set
new_buff_index  The new value for buff_index

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

RETURN VALUES
EXTEND_DATA_OK if the new value is acceptable and assigned EXTEND_DATA_OUT_OF_RANGE otherwise

EXAMPLES
xt_ff_t      xt_ffile;
ssize_t         new_buff_index;
if ( xt_ff_set_buff_index(&xt_ffile, new_buff_index)
        == EXTEND_DATA_OK )
{
}
