NAME
slow5_idx_load_with - loads the index file for a SLOW5 file for a user specified file path for the index
SYNOPSYS
int slow5_idx_load_with(slow5_file_t *s5p, const char *pathname)
DESCRIPTION
slow5_idx_load_with() loads an index file located at pathname for a SLOW5 file pointed by s5p into the memory from the disk and associates the index with s5p. If the index file is not found, it will error out.
RETURN VALUE
Upon successful completion, slow5_idx_load_with() returns a non-negative integer. Otherwise, a negative value is returned.
NOTES
slow5_errno will be set in future to indicate the type of error that occurred.
EXAMPLES
#include <stdio.h>
#include <stdlib.h>
#include <slow5/slow5.h>
#define FILE_PATH "examples/example.slow5"
#define INDEX_PATH "indexes/example.slow5.idx"
int main(){
slow5_file_t *sp = slow5_open(FILE_PATH,"r");
if(sp==NULL){
fprintf(stderr,"Error in opening file\n");
exit(EXIT_FAILURE);
}
int ret=0;
ret = slow5_idx_load_with(sp, INDEX_PATH);
if(ret<0){
fprintf(stderr,"Error in loading index\n");
exit(EXIT_FAILURE);
}
//...
slow5_idx_unload(sp);
slow5_close(sp);
