Module risc0_zkvm_platform::syscall

Modules

• bigint
• ecall
• halt
• nr
• reg_abi

Structs

• Return
  Returned registers (a0, a1) from a syscall invocation.
• SyscallName
  A UTF-8 NUL-terminated name of a syscall with static lifetime.

Constants

• DIGEST_BYTES
• DIGEST_WORDS
• IO_CHUNK_WORDS
  Number of words in each cycle received using the SOFTWARE ecall
• MAX_BUF_BYTES
• MAX_BUF_WORDS
• MAX_SHA_COMPRESS_BLOCKS

Functions

• sys_alloc_aligned^⚠export-syscalls
  Safety
• sys_alloc_words
• sys_argc
  Retrieves the count of arguments provided to program execution.
• sys_argv^⚠
  Retrieves the argument with arg_index, and stores as much of it as it can it in the memory at [out_words, out_words + out_nwords).
• sys_bigint^⚠
  Safety
• sys_cycle_count
• sys_getenv^⚠
  Retrieves the value of an environment variable, and stores as much of it as it can it in the memory at [out_words, out_words + out_nwords).
• sys_halt
  Safety
• sys_input
• sys_log^⚠
  Safety
• sys_panic^⚠
  Safety
• sys_pause^⚠
  Safety
• sys_rand^⚠
  Safety
• sys_read^⚠
  Reads the given number of bytes into the given buffer, posix-style. Returns the number of bytes actually read. On end of file, returns 0.
• sys_read_words^⚠
  Reads up to the given number of words into the buffer [recv_buf, recv_buf + nwords). Returns the number of bytes actually read. sys_read_words is a more efficient interface than sys_read, but varies from POSIX semantics. Notably:
• sys_sha_buffer^⚠
  Safety
• sys_sha_compress^⚠
  Safety
• sys_verify_integrity^⚠export-syscalls
  Send a ReceiptClaim digest to the host to request verification.
• sys_write^⚠
  Safety
• syscall_0^⚠
  Invoke a raw system call
• syscall_1^⚠
  Invoke a raw system call
• syscall_2^⚠
  Invoke a raw system call
• syscall_3^⚠
  Invoke a raw system call
• syscall_4^⚠
  Invoke a raw system call
• syscall_5^⚠
  Invoke a raw system call
