This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Private Function

resolveFromName

Doc Source

Private Function

std.dynamic_library.ElfDynLib.resolveFromName

fn resolveFromName(io: Io, path_or_name: []const u8, LD_LIBRARY_PATH: ?[]const u8) !Io.File

This implements enough to be able to load system libraries in general Places where it differs from dlopen:

DT_RPATH of the calling binary is not used as a search path
DT_RUNPATH of the calling binary is not used as a search path
/etc/ld.so.cache is not read

Params

io: Io
path_or_name: []const u8
LD_LIBRARY_PATH: ?[]const u8

File

dynamic_library.zig:200
