NAME

bl_sam_init() - Initialize all fields of a SAM object

LIBRARY

#include <biolibc/sam.h>
-lbiolibc -lxtend

SYNOPSIS

void    bl_sam_init(bl_sam_t *alignment)

ARGUMENTS

alignment   Pointer to bl_sam_t structure to initialize
seq_len     Length of sequence and quality strings
field_mask  Bit mask indicating which fields will be used

DESCRIPTION

Initialize a bl_sam_t structure, allocating memory for sequence and quality strings according to seq_len. Passing a seq_len of 0 prevents memory allocation from occurring.

Only BL_SAM_FIELD_SEQ and BL_SAM_FIELD_QUAL are meaningful bits in field_mask, as they determine whether memory is allocated. All other fields are unconditionally initialized to 0, NULL, or blank.
