    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

### Usage

```c
#include "stdlib/blas/base/xerbla.h"
```

#### c_xerbla( info, \*rout, \*form, ... )

Prints an error message and exits the program.

<!-- run-disable -->

```c
c_xerbla( 1, "dgemm", "" )
```

The function accepts the following arguments:

-   **info**: `[in] CBLAS_INT` argument index.
-   **rout**: `[in] char*` name of routine.
-   **form**: `[in] char*` null-terminated character format string.
-   **vargs** list of arguments to format in the format string.

```c
void c_xerbla( const CBLAS_INT info, const char *rout, const char *form, ... );
