是的，您可以使用openssl的接口来生成CSR数据。以下是一个简单的Linux C代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <openssl/evp.h>
#include <openssl/rsa.h>
#include <openssl/x509.h>
#include <openssl/x509v3.h>

int main() {
    EVP_PKEY *pkey = NULL;
    RSA *rsa = RSA_new();
    BIGNUM *bn = BN_new();
    X509_REQ *req = NULL;
    X509_NAME *name = NULL;
    const char *country = "CN";
    const char *state = "Beijing";
    const char *locality = "Beijing";
    const char *organization = "CSDN";
    const char *organizational_unit = "IT";
    const char *common_name = "example.com";
    int ret = 0;

    BN_set_word(bn, RSA_F4);
    RSA_generate_key_ex(rsa, 2048, bn, NULL);
    pkey = EVP_PKEY_new();
    EVP_PKEY_set1_RSA(pkey, rsa);

    req = X509_REQ_new();
    name = X509_REQ_get_subject_name(req);
    X509_NAME_add_entry_by_txt(name, "C", MBSTRING_ASC, country, -1, -1, 0);
    X509_NAME_add_entry_by_txt(name, "ST", MBSTRING_ASC, state, -1, -1, 0);
    X509_NAME_add_entry_by_txt(name, "L", MBSTRING_ASC, locality, -1, -1, 0);
    X509_NAME_add_entry_by_txt(name, "O", MBSTRING_ASC, organization, -1, -1, 0);
    X509_NAME_add_entry_by_txt(name, "OU", MBSTRING_ASC, organizational_unit, -1, -1, 0);
    X509_NAME_add_entry_by_txt(name, "CN", MBSTRING_ASC, common_name, -1, -1, 0);

    ret = X509_REQ_set_pubkey(req, pkey);
    if (ret != 1) {
        fprintf(stderr, "Failed to set public key\n");
        return -1;
    }

    ret = X509_REQ_sign(req, pkey, EVP_sha256());
    if (ret != 1) {
        fprintf(stderr, "Failed to sign CSR\n");
        return -1;
    }

    FILE *fp = fopen("example.csr", "wb");
    if (!fp) {
        fprintf(stderr, "Failed to open file\n");
        return -1;
    }
    PEM_write_X509_REQ(fp, req);
    fclose(fp);

    X509_REQ_free(req);
    EVP_PKEY_free(pkey);
    RSA_free(rsa);
    BN_free(bn);

    return 0;
}

该代码将生成一个2048位RSA密钥对和一个包含您提供的信息的CSR文件。在代码中，您需要提供以下信息：

- `country`: 国家名称
- `state`: 省/州名称
- `locality`: 城市/地区名称
- `organization`: 组织名称
- `organizational_unit`: 组织单位名称
- `common_name`: 常用名称 (通常是您的域名)

您可以使用`openssl req -in example.csr -noout -text`命令查看生成的CSR文件的详细信息。
