Libbpf userspace function btf__add_enum64

1.0.0

Append new BTF_KIND_ENUM64 type to BTF object.

Definition

int btf__add_enum64(struct btf *btf, const char *name, __u32 bytes_sz, bool is_signed);

Parameters

  • btf: pointer to a struct btf object
  • name: name of the enum, can be NULL or empty for anonymous enums;
  • bytes_sz: size of the enum, in bytes.
  • is_signed: whether the enum values are signed or not.

Return

>0, type ID of newly added BTF type; <0, on error.

Usage

Enum initially has no enum values in it (and corresponds to enum forward declaration). Enumerator values can be added by btf__add_enum64_value immediately after btf__add_enum64 succeeds.
