Function rust_htslib::htslib::bcf_calc_ac

pub unsafe extern "C" fn bcf_calc_ac(
    header: *const bcf_hdr_t, 
    line: *mut bcf1_t, 
    ac: *mut c_int, 
    which: c_int
) -> c_int

bcf_calc_ac() - calculate the number of REF and ALT alleles @header: for access to BCF_DT_ID dictionary @line: VCF line obtained from vcf_parse1 @ac: array of length line->n_allele @which: determine if INFO/AN,AC and indv fields be used

Returns 1 if the call succeeded, or 0 if the value could not be determined.

The value of @which determines if existing INFO/AC,AN can be used (BCF_UN_INFO) and and if indv fields can be splitted (BCF_UN_FMT).
