+# RzSyscall
+
+`RzSyscall` provides functionality to manage system calls and system registers for different architectures and operating systems. It allows mapping between syscall numbers and names, as well as resolving system register values.
+
+## Architecture
+
+The core structure is `RzSyscall`, which holds the database of system calls loaded from SDB files.
+
+### Key Structures
+
+- `RzSyscall`: Main handle, contains the SDB database and context information (OS, Arch, CPU, Bits).
+- `RzSyscallItem`: Represents a single system call with its name, number, arguments, etc.
+- `RzPath`: Helper structure used during initialization to locate SDB files.
+
+### Workflow
+
+```mermaid
+graph TD
+    A[RzPath New] --> B[RzSyscall New]
+    B --> C{rz_syscall_setup}
+    C -->|Locates SDBs| D[Load Syscall DB]
+    D --> E[Ready for Query]
+    E --> F[rz_syscall_get]
+    E --> G[rz_syscall_get_num]
+```
+
+## Usage
+
+Using `RzSyscall` involves the following steps:
+
+1.  **Initialize `RzPath`**: Create an `RzPath` instance to help locate system files.
+2.  **Create `RzSyscall`**: Allocate a new `RzSyscall` instance.
+3.  **Setup**: Configure the instance with the desired OS, Architecture, and bitness using `rz_syscall_setup()`.
+4.  **Query**: Use functions like `rz_syscall_get()` or `rz_syscall_get_num()` to resolve syscalls.
+
+## Example: Resolving a Syscall on Linux x86_64
+
+```c
+#include <rz_syscall.h>
+#include <rz_util.h>
+#include <stdio.h>
+
+int main(void) {
+	// 1. Create RzPath to locate SDB files
+	RzPath *path = rz_path_new();
+	if (!path) {
+		fprintf(stderr, "Failed to create RzPath\n");
+		return 1;
+	}
+
+	// 2. Create RzSyscall instance
+	RzSyscall *sc = rz_syscall_new();
+	if (!sc) {
+		fprintf(stderr, "Failed to create RzSyscall\n");
+		rz_path_free(path);
+		return 1;
+	}
+
+	// 3. Setup for Linux x86_64
+	// rz_syscall_setup(sc, path, arch, bits, cpu, os)
+	if (!rz_syscall_setup(sc, path, "x86", 64, NULL, "linux")) {
+		fprintf(stderr, "Failed to setup RzSyscall for linux-x86-64\n");
+		rz_syscall_free(sc);
+		rz_path_free(path);
+		return 1;
+	}
+
+	// 4. Query a syscall (e.g., write = 1 on Linux x86_64)
+	int syscall_num = 1;
+	RzSyscallItem *item = rz_syscall_get(sc, syscall_num, -1);
+	if (item) {
+		printf("Syscall %d on Linux x86_64 is '%s'\n", syscall_num, item->name);
+		rz_syscall_item_free(item);
+	} else {
+		printf("Syscall %d not found\n", syscall_num);
+	}
+
+	// Cleanup
+	rz_syscall_free(sc);
+	rz_path_free(path);
+	return 0;
+}
+```
+
+## Syscall Database (SDB)
+
+The syscall database is stored in `librz/syscall/d` as plain text files with the `.sdb.txt` extension. These files are compiled into binary SDB files during the build process.
+
+### File Format
+
+Each line represents a syscall definition in the following format:
+
+```
+name=swi,num,args,types
+```
+
+- **name**: Name of the syscall (e.g., `write`, `open`).
+- **swi**: Software interrupt number (usually `0x80` for Linux x86).
+- **num**: Syscall number.
+- **args**: Number of arguments.
+- **types**: String representing the types of arguments (optional).
+
+**Key-Value Pairs for Lookup:**
+
+The SDB file assumes specific keys for lookup:
+- `_`: Stores the default SWI number (e.g., `_=0x80`).
+- `name`: Lookup by name (e.g., `write` -> `0x80,1,3,izi`).
+- `swi.num`: Lookup by SWI and number (e.g., `0x80.1` -> `write`).
+
+### Adding a New Database
+
+1. Create a new file in `librz/syscall/d/` named `<os>-<arch>-<bits>.sdb.txt`.
+2. Populate it with syscall definitions.
+3. Add the new file to `librz/syscall/d/meson.build` to ensure it gets compiled and installed.
