El patrón compilado ocupa un área estática, el búfer del patrón, que se sobreescribirá en la próxima llamada a .BR re_comp . Si .I exreg es .BR NULL , no se efectúa ninguna operación y los contenidos del búfer del patrón no se alteran. .B re_exec se usa para saber si la cadena acabada en cero a la que apunte .I cadena concuerda con la expresión regular previamente compilada .IR exreg . .SH "VALOR DEVUELTO" .B re_comp devuelve .B NULL tras una compilación exitosa de .I exreg y en otro caso devuelve un puntero a un mensaje de error apropiado. .B re_exec devuelve 1 si hay concordancia, cero si hay un fallo. .SH "CONFORME A" BSD 4.3 .SH "VÉASE TAMBIÉN" .BR regex (7), .B "GNU regex manual"
