Module syscall_api 

Syscall Wrapper Types for VeridianOS

Type-safe wrappers defining the VeridianOS system call interface. These are contract definitions for user-space libraries; the actual implementations use architecture-specific syscall instructions at runtime.

NOTE: Many types in this module are forward declarations for user-space APIs. They will be exercised when user-space process execution is functional. See TODO(user-space) markers for specific activation points.

Structs

PackageInfo

Basic package information returned by sys_pkg_query.

Enums

SyscallError

Error codes returned by VeridianOS system calls.

Functions

sys_cap_create

Create a new capability with the specified rights bitmask.

sys_cap_grant

Grant a capability to another process, enabling cross-process resource sharing.

sys_cap_revoke

Revoke a capability and all capabilities derived from it.

sys_close

Close an open file descriptor, releasing associated resources.

sys_exec

Replace the current process image with a new program loaded from an ELF executable.

sys_exit

Terminate the current process with the given exit code.

sys_fork

Fork the current process, creating a new child process.

sys_getpid

Return the PID of the calling process.

sys_ipc_receive

Receive a message from an IPC endpoint.

sys_ipc_send

Send a message to an IPC endpoint.

sys_mmap

Map memory into the calling process’s virtual address space.

sys_munmap

Unmap a previously mapped memory region from the calling process’s address space.

sys_open

Open a file or directory, returning a file descriptor.

sys_pkg_install

Install a package by name from the configured repositories.

sys_pkg_query

Query information about a package by name.

sys_pkg_remove

Remove an installed package from the system.

sys_read

Read data from an open file descriptor.

sys_wait

Wait for a child process to exit and collect its exit status.

sys_write

Write data to an open file descriptor.

Type Aliases

SyscallResult

Result type for system call operations.
